Yes, I think so too.
The example I gave above, from a remain site- has been followed all day by a flood of similar ones. In short- we tried to reason, debate sensibly, build bridges, listen ... but after so long, we've given up with our parents, grandparents, siblings, relatives, colleagues and friends who have turned almost violent in their exchanges, and have shown strong signs of xenophobia and prejudice, ignorance and irrationality.
This of course does not mean that all leavers are racist, ignorant or irrational- but those who have shown that they are- are being cut out after months and months of trying to have a sensible discussion. Some things you can agree to disagree about - sheer and blatant racism- I'm afraid, I can't.
