Why is it that I can’t comment freely on YouTube?

Why is it that I can’t comment freely on YouTube? I don’t mean to swear or throw slurs but Youtube flags my comment even though the only words I said involves “kill”, “death”, “destruction”, “pain”, “sad”, etc. while others can swear and throw slurs everywhere.

Keep in mind that I already tried using both a PC and a smart phone but it still didn’t work.

Seriously, what should I do? Is there a secret? Am I missing out on something?
