As you say:

Calling/labeling “religious” those who are non-religious makes no sense. It’s a cheap shot and those who use such cheap shots are often the ones who are irrational and detached from an alternative (opposing) point of view. When logic doesn’t work in an argument, then cheap shots get used, or ad hominem attacks.

And that is exactly what you are doing here.

Now compare that to those who follow Stallman’s cult-like teachings where he bastardizes the language and claims that to be “Free” one must succumb to his limitations. Just utter nonsense. Nothing wrong with the GPL – it is truly a masterful piece of work and a fine choice for protecting your IP – but it is not more “free” than, say, licenses which allow for more freedoms, such as the BSD license (also a fine choice). And Stallman has pushed his cult-like notion that all software developers, ideally in his view, would be forced to follow his ideas. His cult-like ideas.

Even Linus Torvalds speaks of this:

There are ‘extremists’ in the free software world, but that’s one major reason why I don’t call what I do ‘free software’ any more. I don’t want to be associated with the people for whom it’s about exclusion and hatred.

If you cannot figure out he is speaking of Stallman and his extremist cult-like followers you do not understand the open source world.
