You are never going to have a meaningful conversation with anyone if you can’t accept that people with different opinions are just that: People with opinions. Most of them aren’t evil. Not deceitful. Just humans who’ve had different experiences than you.
If you label all these people as evil then indeed, violence against them is the only option you have. You create a world as radical, judgmental, and toxic as the sad history you’re trying to rectify by insulting and shutting up people who just express honest and valid concerns.
