Bristol is supposed to be very nice, Brighton is probably the most LGBT friendly city in the UK from what LGBT friends have told me, London is generally accepting of everyone but can be expensive.

Obviously do some more research, but I figure it’s worth putting those two cities on your radar.

I think this is why the OP mentioned buy less stuff and travel less, these two directly reduce the demand for environmentally harmful goods and services, reducing the ecological impact of the companies which issue the shares that make the billionaires in question billionaires.

It’s kinda disappointing to see a post about good actionable advice to do the best you can to reduce climate change and the first reply on Lemmy is non actionable (and more controversially; to my mind irrelevant) advice to assassinate billionaires.

Of course; the post is calling out people like Eskimofry for lazy unfounded pessimism so they are going to reach for the same lazy unfounded dismissal in an attempt to deflect that criticism
