Your assumption here, that I, or other leave voters, feel we have any need to proove that bigoted, stereotyped, condescending, patronising comments about us are wrong says an awful lot about your attitudes. I feel no need to proove you or anyone else wrong. If you want to cling on to bigoted, narrow minded views and carry on asking questions whilst throwing insults at the same time, and then expressing faux outrage that people don't want to answer your questions, knock yourself out.
Yes, of course it is bear.
Perhaps, here and bear try your tactic in real life and report back on how far it gets you. Try engaging people in conservation, but make sure to pepper your comments with insults. Then complain that the subjects of your insults don't want to engage with you, and state that this means they don't have any answers.
Perhaps try this one on your local high street:
Do you know the way to the nearest chemist, you stupid arse? Oh, she just walked off - well she obviously doesn't know where the chemist is 
Let me know how you get on. No don't bother, wasted enough time, hiding thread.
