chapter 19-20

The first encounter the children(Scount and Dill)had with Dolphus Raymond was when Dill-shocked and indignant at Mr Gilmer's harsh words and condescending tone towards Tom Robinson-cried.Scout brought him out for a breather.It was under the shade of the trees that they met Dolphus Raymond.

Dill exhaled patiently.'I know all that,Scout.It was the way he said it made me sick,plain sick.'
...
'I know what you mean,boy,'
...
It belonged to Mr Dolphus Raymond.
...
'You aren't thin-hided,it just makes you sick,doesn't it?'
Excerpt from pages 219-220

From this excerpt it is obvious that Dolphus Raymond is not a racist.Instead,he is against racial predjudice.He can't endure it because it made him 'plain sick'.

Scout,wary of Dolphus Raymond(an infamous wealthy merchant and drunkard),warned Dill when he sipped the drink Dolphus Raymond offered to calm him.Scout,sure that he was 'evidently taking delight in corrupting a child' was suprised when she learnt that all Dolphus Raymond drank from his sack was Coca-Cola instead of beer.When the children knew the truth about Dolphus Raymond's prefered choice of fluid,he asked them to keep it a secret,fearing that it would ruin his reputation.'You little folks won't tell on me now,would you?It'd ruin my reputation if you did.'(pg221)

From this,it is observed that Dolphus Raymond has a reputation which was shrouded by rumours.However the revelation of him not being an alcoholic proved these rumours false.Also from this,we can tell that Dolphus Raymond has a kind heart as he offered to quell Dill's trauma by presenting him with Coca-Cola.By conciously revealing his secret to the children illustrates his trust in them as he felt a sense of connection with the children because they were able to empathise with him.'I know what you mean boy,'(pg220)

Later,Dolphus Raymond tells them why he pretends to be like he is.'Why do you do like you do?'(pg221)He replied 'I try to give em' a reason,you see.It helps folks if they can latch on to a reason...folks can say Dolphus Raymond is in the clutches of whiskey-thats why he won't change his ways.He can't help himself,thats why he lives the way he does.'(pg221)

From this it can be seen that Dolphus Raymond doesn't integrate well into the social borders of Maycomb.Thus he refuses to live with them,instead he chooses to 'live the way he does',giving people the impression that he is a drunkard even though he knew it would result in rumours and different treatment from people.Although he cannot stand the injustice that wrecks Maycomb,he fails to 'rescue' the victims(blacks)by adopting the role of their 'hero' by openly standing up to the racial prejudice(aka Atticus Finch).
Instead,he chooses to create a personality that is synomynous with drunkardness and incoherence to escape from the injustice and evil he witnesses.This suggests that although he hates racism,he does not have enough courage and/or is simply jaded to do anything about it.
The only form of his disapproval of the racism in Maycomb is in the form of his rebellious streak when he chooses to defy social norms(cohabitating with a black woman)in the black community.'...they could never,never understand that I live like I do because thats the way I want to live.'(pg221)

In his acknowledgement that Dill cried, he noted ' Things haven't caught up with that ones instinct yet.Let him get alittle older and he won't get sick and cry.'(pg222) Later,he told Scout that 'you haven't seen enough of the world yet.'(pg222)

From his confidence that Dill 'won't get sick and cry' when he is older suggests that Dolphus Raymond had gone through what Dill just went through.Shocked and indignant with how the whites imperiously treat the blacks,he must have felt disgusted and expressed sadness at their attitude towards them.
However,he must've realised that being sick and crying won't remedy the predicament.Thus he had given up on evincing his emotions towards such evil.
His remark on Dill not getting sick and crying when hes older shows that Dolphus Raymond has endured such cruel practices for a long time till he is used to them to the extent that he would be able to control his emotions although he is fervently against it.
In his response to Scout,he expresses how he has become jaded over the years.It shows he views the world as evil and cruel.In becoming cynical after constantly witnessing the corruption in the world and losing all hope in the good that is still in it(evident in Atticus's fight against racism in his defence of Tom Robinson,Mrs Dubose courage in her battle against her morphine addiction,etc), he is stripped off his happiness and joy as all he sees around him is evil.
Thus in this light,Dolphus Raymond is a mockingbird as he simply reacts to his surroundings,'echoing' and 'imitating' after observing the horrible things that took place by sacrificing his joy and weaving a whole new personna that enables people to misunderstand him and breaks his comfort zone.
He is also a figure who is destroyed by the callousness of the world,resulting in him being vunerable,exposed to the perils of unhappiness,bitter and resentment.The consequences he has to face.
'Shoot all the bluejays you want,if you can hit em,but remember its a sin to kill a mockingbird.'
In this case,it'd be easy to kill Dolphus Raymond aka the mockingbird as he is defenceless in the cruely of the world,marred by the hatred and prejudiced he feels.
