Yeah, people on the internet usually don't double check or give a lot of time to things, often taking Twitter screenshots and article headlines at face value. I often find myself doing this too. Everyone doesn't have the free time to factcheck everything they see, and we are especially vulnerable to having our brain fill the gaps with biases.

Saying "Idk man" and moving on is the best strategy for these cases. Second best is probably digging through the internet for clues like some deranged idiot.

Plus, he wants us to react to him. Doesn't matter if the reaction is positive or negative. Don't feed the troll and all.
