The last line of their comment explains it: "The only problem is animals gotta teach other animals about the crossing and until they do they won’t use it." The comic is showing a deer being confused by the crossing and another deer teaching

I'd assume the joke is that deers don't usually teach using a whiteboard? I don't think it's that funny either but there's not much to get, it's just a cute drawing.

You have my full blessing to go forth and create such a comic ༼ つ ◕_◕ ༽つ

I think you're just being obtuse and pedantic for your own sake, if you're really curious you could very easily look this information up. Please stop being like this, you don't have to be this way. Touch grass for fucks sake, good luck out there, must be tough being an insufferable git.

If they mention something that you're not familiar with, e.g. an actor or a singer you don't know or don't know why they are being brought up, you could try asking them more follow up questions about it.

In the same way you enjoy sharing your interests with other people, other people also enjoy sharing theirs. If you show an interest in what they're talking about, you might learn something interesting about a new topic and you would be able to more easily share something you know that is relevant to what they are talking about if you know more about their interests.

Except you're not causing anyone to question their beliefs, you're just being intentionally obnoxious. If you wanted to provide some counter evidence to their point that would be a solid way to cause people to reconsider. As is I doubt you are being honest with your intention, even if to yourself. Maybe talk about it in therapy?

No, it's actually more your general tone and lack of desire to actually put forth any stance of your own that I find obnoxious, but go off bud. Hope you're enjoying yourself, what a way to spend an afternoon, just responding to dozens of people being as annoying as you possibly can. You can deny it obviously, but I do genuinely hope you find better ways of spending your time.

The idea that moderating slurs on an online forum is a stepping stone to an authoritarian hellscape really requires a special kind of brain worms
