I find that terribly narrow minded. It's not about "happiest". I've tried almost all of those before, several of them in multiple ways. I don't like the taste nor texture. So since I don't like the taste of what you like I am thusly being selfish and blocked from helping myself and the world?
This isn't how you win people over to your side. This is the type of thing that actually reinforces someone's opinion and makes it worse getting through to them.
Instead of trying to make yourself sound better than the person you want to convince of your position, you would be better off trying to find common ground and working from there.

Best of luck.
