its not being used as a slur , because its really obvious that its being used to just give a misleading title to the picture the entire point of the post and its not being derogatory towards the trans community in anyway , its just a funny comparison as to how it looks like a trans woman getting a blow job , it doesnt say that being trans is something to be ashamed of or to be ridiculed . there is no malice in the context . yes it is labelling , but it then comes down to the whole argument of you can only call someone a labelling name if you also identify with that label which is just stupid . its the intent behind the use that matters most . you could easily call someone anything in a nice way but if your intent is to abuse the way you said it then you are an ass , but if your intent is , like this , completely innocent then there should be no reason for anyone to get offended
