When you're in parliamentary/house sessions (or whatever your democracy/society/state has), sure, argue and object to everything. There you have what Americans are so crazy about, "Freedom of Speech" and all that.
But outside of that, in private life, most people would find you very cumbersome to deal with if you challenge, object or argue with things that people state about themselves. If I say I'm 32 years old and you try to argue against me, I'll eventually just ignore and shun you, because who has the time to deal with such inconsequential stuff?
I did say "within reason"... which I realise is doing a lot of heavy lifting.
Reasonable people can disagree on that question, but the law will protect a company that fires an individual for crossing that line while the rest of society is arguing over where the line should be. That's just how law works in general.
