Is there a general name for that shape of argument? It or something close to it seems to be a recurring pattern.

• "People who can manage their lives will, despite MMOs.". (People who lose time playing MMOs are bad at managing life, so they would've lost the time anyway.)

• "There's only two possible outcomes for their relationship. They split, or they stay together forever. If it's split, then the sooner it happens the better for everyone. If it's stay, then my meddling won't matter.".

• "No one you would want to meet would find you boring.".

(Edit: removed opening "also".)
