Saying someone should respect a religion doesnt infringe on personal freedom. Creating a law that says you must is an infringement.
I am not religious, but I use to work with soneone who was. She would speak about praying to God and her religious holidays, but she never forced others to change their actions around her. She believes being gay is against God, but she would treat gay coworkers with the same respect as everyone else. That is what respect and tolerance is, simply letting other people live their life. She was one of my favorite people and we would often converse about a variety of subjects, but I never told her she was wrong to believe what she did.
Saying we should respect others is fine, Im all for that, as long as we are still allowed to question each others beliefs. The problem with PC culture is that it doesnt actually call for respect, it calls for acceptance and agreement. You can be polite in an unPC way and you can be rude in a PC way.
Another couple of coworker I had werr Muslim. The observed the holidays and would periodically fast. Again, they did not try to shame me for what did or did not believe, and I respected that they held certain religious beliefs. I was the manager so I ensured thatbtheir schedules accommodated their religious needs, not because I feared a lawsuit, but because its the right thing to do. I respected them for who were.
I often see the "tolerant" left bash Christianity and sometimes Judaism, not so much Islam. They say that religious people are stupid and intelligent people are atheists. Well, in my experience, that isnt true. There are stupid atheists and smart religious people and vice versa.
That being said, if you dont want to respect another religion's texts you dont HAVE to, but you should in polite society. I would never support a law that banned bible burning, but I wouldn't burn a bible just for fun either.
