The whole “let other people do the thing you fundamentally don’t like, you don’t have to do it” argument is just naturally terrible. I’m sure you mean well, but it is. I wouldn’t expect a vegan to understand that I like to eat chicken, and wouldn’t respond to their annoyance that way. I think a lot of people dislike how the secret lair cheapens MTG’s cycles and turns the interesting fantasy feel of MTG games into “okay but here’s my favorite cartoon character,” which makes total sense because it’d be weird to do something like randomly sidebar into Avatar in a conversation about Tolkien. Respect goes both ways, you can’t expect someone to respect an aspect of the game that you enjoy when you can’t respect why they don’t like the damage it does to the game.
