Do you get sick of people misrepresenting what you said on purpose?

Yes, and I am acquainted with someone who has done that many times...both publicly and privately. I find it to be a most particularly obnoxious sort of deceit.

Sometimes when I share something personal someone will appear and judge me like they know anything at all. I just tell them to eff off and block them.

That is an old debate trick and I just tell them so.
