Let me put it another way. If you do not care about whether or not you insult a person - you can look at what you are doing from a different perspective. What are you trying to achieve? That people you are talking with change their opinions? To promote your point of view? Then you achieve nothing. I actually agree with you about religion, but your attempts to persuade other people are futile at best. If you actually want to make other people listen - it is necessary to speak respectfully. It will be actually beneficial for you in the end.
If you just keep silent when the opinions about restricting freedom of expression are being pushed then you'll run into the effect, which cause devs having an impression that "community wants us to make such restrictions and we're making games for them". This is how the whole "vocal minority with agenda works".
