Should a person condemn another person religion?

Most people a serious about their religion. First we must respect that fact. Rather than condemn help the person make adjustment regarding their belief by reasoning with them. They must come to the conclusion themself. You don't want to give you opinion. You should show them from their Bible was is written. 2 Timothy 3:16, 17

16 All Scripture is inspired of God+ and beneficial for teaching,+ for reproving, for setting things straight,* for disciplining in righteousness,+ 17 so that the man of God may be fully competent, completely equipped for every good work.

There is no "should" about it, because it's a totally subjective thing. Personally I think that condemning an entire religion is short-sighted and narrow-minded, but that's just my personal opinion.

It rather depends. If someone is quoting his religion which lies about your religion's beliefs, you have every right to condemn what he says as lies and to prove him wrong.

All religions are just superstitious nonsense. Condemn them all.

Depends on the religion but I can tell you that everyone should be able to condemn another person's religion. Religions are ideas and ideas are ALWAYS subject to criticism.

Yes, criticism of ones religion is perfectly fair.

Of course not, religion is a pointless waste of time. It's harmful & a burden on society.

If you think so then, yes - if you can do it respectfully.

Respecting other people is important. Respecting ignorance is not.

An idea and claims should not be beyond analysis and criticism just because they include magical beings. You can criticize a religion without persecuting people who follow it.

No.

All religions have something about not judging other people. This would apply to criticizing other peoples' beliefs even if you don't agree with them.
