I am never pissed off just because someone has a different view. I'm not a teenager anymore!
Of course I'm human, and it sure feels nice if someone agrees with me: a thumbs up or a good word of appreciation brings a warm cozy feeling and a smile. But in all those decades of my life I've learned that we all think differently, and that it's OK.
However, if someone has opposing views, they can say "I disagree because..." or whatever. Either continue a civil conversation, where each party explains their opinion, or just... leave it alon, not comment at all. Not just insult another person out of the blue.
