This makes me think, trolls are everywhere on social media. They actually feed on disagreeing with people online. I mean, I have really close friends that troll my opinion sometimes, but it's fine, 'cause I know them and all they are doing is trying to grab my attention. So anyways, I think it is important to not get too emotional about people that disagree with your opinion on something. A good way of facing this, in my opinion, is by actually listening to what they have to say, I mean, maybe you or they can learn something interesting about the topic! Or, you can simply ignore and choose your battles wisely ;)
