Social conservatism is a political philosophy. The rules explicitly stated that politics are not allowed. Tony used to allow politics in Novelupdates, but it quickly devolved into name-calling, insults, and all around bad vibes that caused some people have long term enmity towards each other. Some even closed their accounts or went missing after being part of such topics. So it was banned there and to avoid the same thing happening here, it's banned here too. The crowd here has already proven that they are easily triggered and can't be trusted to hold civil discussions.
Just go to reddit if you want to deal in those topics. Unlike here, if you want to agree with yourself, you can just make another account or delete your current account and act like a rando who just happened to agree with yourself and accuse the others as idiots. Over here, your account is tied to the stories you post. If people hate your politics, you stories could get thumbed down. And if some authors say something different from what the majority believes, he could get harassed and as a result, deletes his account as well as his stories.
As a fiction story platform, it's best to just avoid all those from the start.
