I couldn't get the link to work. In my opinion, too many people just don’t seem to realize the difference between insulting ideas that people have and the people themselves. Ideas always should be fair game but people should never be attacked for how they were born.

Religion is becoming a government..

It is beyond religious, it's a cult of extreme danger & the most threatening thing to democracy alive in the world today!
Sam Harris is a Liberal atheistic neuroscientist who has repeatedly spoken against the way PC is infringing on free speech.
Douglas Kear Murray winner of the Lambda Literary Award is a gay british atheist who speaks against PC.
Carl Benjamin is a liberal atheist Anti-PC journalist & commentator.
Benjamin Aaron Shapiro is an American Jewish conservative Anti-PC political commentator.
Milo Yiannopoulos is a Gay Atheist Librarian, who is ultra politically incorrect.
Jordan Bernt Peterson is an Anti-PC professor of psychology at the University of Toronto.
Anyone who listens to what these renowned individuals have to say about the dangers of "POLITICAL CORRECTNESS", would have to be insane not to realize the threat which it possess.

No, I don't think so. The people who spout "politcal correctness" seem to be religious and more narrow in their thinking, however, I don't want to put that label on the ones who accuse others who they don't believe in the thoughts as "PC". It's not a religion but just a narrow-minded view.

It is. Heck, even feminism nowadays is becoming more like a religion.

A religion is usually defined as a faith-based worldview with a strict moral code, sacred objects/places/rituals, and the belief in one or more supernatural entity/phenomena. I used this definition because virtually all acknowledged religions are like this, and under this definition, political correctness does not count as one.

I think certain "Dogmas" are valid. Is it dogma to say that homosexuality isn't evil or a sickness? Maybe it is but is it a good idea to validate the beliefs of others who believe it's a sin by opening it up for debate? Have we not had enough debate on these types of issues to conclude that it is entirely natural? Let them whine and complain that it's dogmatic. I have no tolerance for people who openly restrict privileges they enjoy just to refuse it to people of a different mindset.
