I administer a forum on a completely different matter/interest. It is very international as it is a very niche interest using equipment that is in the main no longer made, so most of us are buying and using - as well as maintaining and repairing - machinery that is simple to complex - and anything from 150 to 20-odd years old.
There has been virtually no mention of anti-vax or conspiracy theories except in the most light-hearted and brief ways; the general impression is of pro-vax and pro-mask which, as the great majority of us on the forum are 'of a certain age', both male and female, seems to be about right for the demographic.
The subject simply wouldn't come up in on-topic discussions, anyway, and we have a formal policy of not talking politics or religion in the off-topic chat sections, except brief, in-passing mentions, or if someone genuinely asks for an explanation of something that is common practice in the other member's country but not in their own.
Yesterday my nice group's peace was disrupted by a member describing how she likes to taunt mask wearers in the supermarket - compounded by commands to DO YOUR OWN RESEARCH! I think lots of us on the forum were shocked by her sudden interjection into a light-hearted off-topic discussion of 'gassy foodstuffs'! Talk about 'hot air'!
Anyway she has been told the facts as they are and if it happens again she will be banned.
