None of us have walked a mile in each other's shoes. If you were born into their body, with their mind, their upbringing and influences, you'd be them. You'd be saying and doing the shit they're saying and doing.
I wasted a lot of time and energy being pointlessly resistant to other people when I was young. Only to realise we're all just being who we are. I'm not saying you should agree with them, or believe the same things as them. I'm just saying go easy, because we're all just trying to get through this shit show. And they're just trying it the best way they know how.
