Gone vegetarian 5 years ago just before the pandemic hit. I've never had any real issues so far and my friend group has mostly switched to vegetarian meals when I'm present. Not because anyone forced them, but because it's a lot easier and there's so much awesome vegetarian food nowadays.
And when we barbecue, everyone brings their own stuff anyway. So that's a non issue as well (I don't care about cross contamination at all)
I don't think I could go full vegan, but in all honesty, I save enough money from not buying meat that I can buy all of my milk and cheese organic and that got rid of pretty much every last one of my moral qualms.
