As long as they are not harmful to others nor force their own on other people then sure.

An example I would bring up is the caste system in India. The people didn't do anyhting in particular that was wrong to the "untouchables". They didn't impose a belief upon them. However, their beliefs told them not to interact with them in any way, which plunged the population in extreme poverty, and forced the intouchables into jobs no one else wanted. This is one of the reasons why I would include that telling people that they are better than others is not okay.

Well, I guess we'd also have to question whether or not a view or belief is crazy. Many people would think that communists are crazy for supporting a stateless, classless society.

Crazy as in harmful to others.

This was also my problem with establishing a methodology of acceptable beliefs. The majority isn't necessarily right, and there isn't necessarily one truth. What seems absurd today may be general knowledge tomorrow.

So, I tried to make a list of things that doesn't seek truth, but rather help keep peace and rationality in society, without defining what is rational.

I think the best approach to anything is to simply criticize it if needed, and to let people the reality behind it. For example, Islam. There's no point in treating everything involving Islam as evil. At the same time, we shouldn't act as though it turns everything into gold.

Also, nice post. So far, I have only seen great responses. Hope it stays like that

If the beliefs are backwards, they should be allowed, but criticised.

If the beliefs are dangerous or infringe on the rights of others, they should be stopped.

The only problem is it's all subjective, and people can twist facts to put pretty much any belief into one of these groups, as I'm pretty sure you all know and see on a regular basis. Politics seem to be losing touch with reality sadly.

Should all beliefs be tolerated? Of course. Because what would you do with the people who held beliefs that you didn't like? Censor them? Isolate them from everyone? Reeducate them? Kill them?

I don't like this sort of "rabbit hole" because it's dangerous to everyone depending who's in power or in the position to determine which beliefs should be tolerated and what should be done about it.

I believe that all beliefs should be tolerated just as long as a belief that people hold doesn't incite extreme violence and actually do it like the nazis did or jihadists do but that doesn't mean I agree with knuckleheads calling any person they want a nazi to justify acting like a dick or attacking them. I've been seeing antifa doing that crap and I hope that movement dies out soon.

I also believe that people should be encouraged to think for themselves, question everything and

If it infers in the rights and freedom of another, no, it shouldn't be tolerated. So, i do think all religion that atempts this should outlawed.

If it doesn't then its harmless. Believe what you want. Beliefs in themselves are not the problem, just nefarious actions against others based on those beliefs are.

It should only be applied if the beliefs are towards self-fulfillment and not harm towards others.
Most, if not all, religions by nature are meant to be self-fulfilling and even helpful towards other people. The one Golden Rule that ALL religions are supposed follow is Respect. Remember the Six Pillars of Character that we learned in middle school (I assume)? I don't know about you guys, but the one Pillar that they hammered home the most for me was Respect. Respect and tolerance towards other people and their beliefs and to not inflict any harm whatsoever based on those differences. And don't take your own beliefs too far.

As long as an individual doesn't cross the line/go too far and try to actually bring harm, physically, mentally, and emotionally towards other people, than their beliefs should be respected and tolerated.
