I meant it in the sense of being unsympathetic towards an opinion (the opinion that there is something unjust about gentrification) not towards the alleged victims of gentrification.
My aim is to express an opinion: That tech workers have a right to live where they want to, and that it's not the right of the local community, or people claiming to represent them, to stop them living where they choose to and frequenting the businesses they choose to.
Now this might be upsetting to people who think of themselves as victims of gentrification, but I didn't formulate this viewpoint for the purpose of upsetting them. If I have to change my viewpoint, or choose not to express it, because someone finds it upsetting, then that is not freedom of speech.
So unless you think that people should be forced to curtail their speech and keep their opinions to themselves, whenever that opinion is offensive to someone who has (or feels they have) suffered some ill fortune, you should stop comparing what I proposed to do with willfully inciting violence towards myself.
