If your belief makes someone else feel bad, is it right to have that belief?

Or if you flaunt your belief to make someone else feel bad and conform, is that right?

If your belief is yours and through general conversation you find out that you share that belief with other people so that there are more people with that belief, is that okay?

If you take all those people who believe the same as you and collectively make other people feel bad and conform is that okay?
