Don’t hesitate to block communities and people if they become annoying to you. People on Lemmy can be very passionate, I would know as I was am sometimes still am included in that set. This combined with how vastly different the culture of each instance can be will lead to strong disagreements sometimes, if you choose to engage do so in good faith but don’t expect to convince anyone of anything lol.

Also you are gonna see some very radical politics if you are not used to that
