You regularly use the laughing emoji to belittle people's posts. You did it to a post of mine on Monday, you do it to people all the time: a cowardly, drive-by "point and laugh", and nothing else. It's rude and it's immature. You wouldn't do it to someone in real life: actively laugh in someone's face when you disagree with what they're saying or find what they're saying to be ridiculous. It's your calling card, you do it all the fucking time, and it's tedious.
Your excuse that you do it because you don't have time to give people the benefit of a reply or explanation as to why you disagree with them (such as what Kenny said to Jinky about Moyes/Everton) is lame. If you don't have time to engage in a conversation, maybe lay off laughing in people's faces.
