I try not to react too strongly to the nastiness ..but am pretty able to handle myself in these exchanges and don’t see it as a virtue always to let some of the name calling and sweeping generalisations go. Its a big call for me because I don’t find it rewarding to be on bad terms with anyone. It sounds like you’re not inclined to adopt a more amiable approach .. whether because of perceived ‘smugness’ on my part or, just as likely, because you despise certain positions I hold. I think it’s a pity. Console yourself, I suppose, with the knowledge that I don’t come on regularly and don’t stick around to much when the toxic stuff kicks in.
