It is tricky because not only should you not respect religions, it is your DUTY to criticize them when they are nonsensical, immoral or otherwise problematic. However, at the same time it is also your DUTY to reject bigotry and harassment against religious people.
Unfortunately, people who are not so smart are also not able to distinguish the two things: criticism of religion and bigotry against religious people. That is how you get people who get personally offended by completely legitimate criticisms of a religion, and it is also how you get people who blatantly harass religious people, claiming they are simply criticizing a religion.
And frankly even for smart people those things can sometimes be difficult to distinguish, especially in the age of social media where the short, unnuanced and confrontational messages get promoted by the algorithms and where the intentions of the sender is more difficult to see.
Therefore it is very important to be super clear with ones message, when it comes to these kinds of topics.
