Nowadays, anyone who disagrees with you isn’t just different or misguided, they are a bad person who must be ostracized/destroyed. Thoughts?
Okay, I’ll bite.
When it comes to opinions or taste, acceptance and tolerance are the keywords. You have no right to impose your views on anyone else, and while you don’t have to respect other people’s views, you do have to accept that he has the rights to his own opinion.
When it comes to morality, religion and anything with a universal truth, this is not the case. While you can’t judge, and you certainly can’t blame, you don’t have to – and often musn’t – accept or tolerate. If anyone is doing something which contravenes Halachah or contravenes Rotzon Hashem, you have every right to condemn the action, and in many cases (for a whole host of reasons) an obligation to protest. In these inyanim, there is no “mind your own business”, there no “live and let live”, and certainly no “respecting his opinion”.
Must they be “ostracized/destroyed”? That obviously depends. Every situation needs to be weighed individually. There are almost always disadvantages and collateral damage by ostracizing and destroying. Sometimes you have to do it anyway. Sometimes you will lose more than you’re gonna gain.
