I live in a very small town so if I want vegetarian here we’re talking a margarita pizza or eggs on toast :P
That said I’ve mostly cut dairy out of my diet, but I don’t remember to check the ingredients of everything I eat so who knows how plant based I am these days. Probably some dairy based butter in some of the things I buy.
I have a lot of stomach issues and unfortunately react somewhat to oat milk, but almond milk (which has other climate issues to my knowledge) and coconut based milk is working very well for me.
History disagrees with you. The truth is that regular protests can be ignored, and voting may not always be very accessible (in non-democracies or because of voter suppression) or effective as a means to achieve change where you live (the US and similar countries because of first past the post voting systems). Direct action is absolutely a necessary and important tool for democracies to be functional whatsoever, and is in fact part of how we ensure good workplace conditions and good wages here in Norway (we have regular strikes as part of bargaining with businesses and the state). Hoping and waiting for things to improve is at best a recipe for nothing to happen.
It seems you think that disruptive protests need to be violent or damaging? Strikes are disruptive and harmless and very effective at changing things for the better.
