That's why you have to fully read posts and the thread to get better context. If a Lakerfan makes a comment saying it's clear LeBron James is better than Michael Jordan, you can have a pretty good idea that it's sarcasm for the purpose of making a point, especially if you read his other, previous posts in the thread.
And if it was only sarcasm you had a problem with, it wouldn't be as big of a problem. You've also misconstrued non-sarcastic comments as well. And, moreover, you are attacking people when you do so. So, it's quite a bit off-putting for you to attack posters when you don't even get what they're saying.
I could have just gotten into a flame war with you, but I realize you're somewhat new to the board and instead I explained the things I said that you misconstrued. There are plenty of posters on here that would have just attacked you right back. Just try to have a little more tact when you get into a discussion or debate. And if you're going to attack and call names, you better be damn sure you know what you're talking about and you understood what the other poster was saying, and more importantly what that poster means.
