Antitheism

[Excited Penguin]

Sure, you can make up your own definitions of words. You can do that.

Or, you can use the definitions we already have. The word you're looking for here is proselytization. Don't let illiteracy and laziness make you think you're a linguist. You're not.

Proselytization is part of it.

And people challenge dictionary definitions all the time.

That's what makes a living language, like English, alive.  It's still evolving.

As opposed to a dead language, like Latin, which has ceased to evolve.

I gotta sleep.

Night, all.

That's not how language works(or evolves for that matter). You don't simply get definitions of words to change to suit your meaning. 

People should challenge dictionary definitions, but they should do so for a good reason. You don't have one. You're simply ignorant of existent definitions of words.
