It can be easy to miss activist events if you're not on mainstream social media and not in a political organisation/network. Even if you're in a city, only some areas will have posters and leafleting groups around.
I'll try and remember to share events here too.
@ShrimpCurler@lemmy.dbzer0.com: Same here. It doesn't even seem to be a central place anymore, the March for Humanity back in August had an estimated 300K marchers, while the Facebook event only listed 2.4K going, 2.8K interested. A link to another site could be shared just as easily, right?
