Hey, dont mention it, I totally get it. This society primes us for the reaction you had, we are constantly ready for a fight, and it is not your fault, it is our conditioning. Finding the way to dispel that curse is the way we get to people's hearts.

Just a side not, I absolutely do not think that radicalism is always stupid, or stupid at all. "Deep roots are not reached by frost", we need conviction and strong ideals, and to further clarify, I do think that veganism is the end goal for a truly advanced society and a healed world and people.

The point is just that to communicate radical ideas we do not need to be in constant anger. Most people respond well when you engage with them and their differences with curiosity, asking questions instead of directly challenging their ways right away. Our communication must be like water, seeking the path of least resistance, yes, but always ending at the sea or a lake. People already know (in some level) that their lifestyles are wrong. That isnt the Epiphany. The epiphany is helping them build up the idea that it is not to late, that they are not irredeemable, and that change is possible.

People do not want to feel irredeemable and as you said, when talking to Normies abt veganism ppl get defensive. It is largely the fault of propaganda, but more critically, it's the shame angle that always, always fails. Responsibility is a different concept, and it melds better in the mind

The only way to change is with grace, compassion, and when needed, severity and discipline, distributed sparingly.

You have to imagine current human society as a collective made of children, fragile, sensitive, impulsive. They will mirror what they perceive, despite your intentions

I hope this helps, and thank you for reading my comment and being graceful
