The problem is vegan is now a Bad Word. I no longer say I am vegan, I say "I don't consume animal products", which seems to get a better reception than "vegan".
I wonder if using the word "vegan" will harm them in the long run from people who take pride in avoiding "woke" vegan things. A cursory glance at the right-wing tabloids in the UK will I think demonstrate that this is a real concern.
