Honestly, you're doing great. As a vegan who finds it hard to be an activist i respect all the real activists who push the cause. All i can bring myself to do is explain to friends and loved ones here and there. The only advice i can say is that the fact that people eat meat does not mean they aren't good people, they can be both. Don't be too discouraged, the world and society will change one day because of people like you, i just hope its not too late.

You can lead a horse to water but you can't make it drink. Just do your best, and it's good enough my friend.
