Haven't set a date yet, but it'll be in around 2 years so it's not right around the corner or anything, but DP and I are both vegans. Neither of us have a problem with other people eating animal products, I don't think I've ever even brought up veganism unless I'm at a restaurant and need to order because I really hate confrontation and I've seen/heard so many cruel and horrible things being said to vegans. That said, we don't want to pay for the guests to be served animal products at our wedding.
Some of my friends think it's unfair and that restaurants etc are pandering to the vegan 'fad' (even though I've been vegan all my life) so I should cater to everyone's dietary requirements. I told them I was considering putting a meat option on the catering form, but that whoever picked it would have to pay for it themselves as I really don't want to give my own money towards that industry. But, my friends also think it's unfair that some people have to pay and others don't.
DP doesn't want to have an animal product option at all, and tbh I would also prefer this, but I want a way of not isolating people who can't go a meal without eating animal products.
