How do I start the vegan conversation with people without it seeming "forced"?

First of all I don't blame the vegans that do force meat eaters to see the problem on the animal industry. The situation is authentically desperate and literally any way to manifest the truth is welcomed. However it's harder for me to tackle the topic with angry people who didn't want to have the conversation. I wish there was a more casual way to bring the vegan topic to the table on any context without making it seem forced or at least not too forced.

Or is there a place on the internet I can go where people will be willing to have this conversation?
