The joke is that they have, if it is a fact and not an opinion, stated a fact.
It is a real, objective fact in the really real reality/world that I am weird.
Now it seems that there is more. Something should follow from that fact:
I am weird, therefore...
But I can't get them to explain more. So I guess it is an opinion after all.
1. I gave you the benefit of the doubt and explained what 'fact' and 'opinion' mean, and how they are used in casual conversation. I did this several times. The fact that you're still doing this means you're not even trying to communicate effectively and so there's no point in trying to have a conversation with you.
2. Take this back over to the other thread, these two train wrecks aren't improved by combining them.
