You have to choose the principles that you live by.
Those principles can include tolerance and compassion. Or they can include hate, fear, intimidation and violence.
Which ones did you choose?
I think even folks who hate, fear, are violent, got that way through some experience. Is that experience invalid? They’ve seen and experienced a world others haven’t. It’s real to them.
Is morality grounds to discount a real perspective?
In my opinion it may be enough to discount it on some matters but one false belief in a sea of a human’s opinions is not enough to discount all of their viewpoint outright.
Forget about other people. What are your principles?
No need to answer.
