The site has created guidelines on what is allowed to be posted in the general forums, including Off Topic. There are some subjects that are not allowed on the site at all and some that are allowed but only within Clubs/groups.
For politics and religion, one suggested group is Open Discussion: https://www.chess.com/club/open-discussion
There some other groups where those subjects are welcomed.
There are a number of old topics where these restrictions have been discussed and the current rule is that they are not allowed outside the appropriate groups.
What is so appalling about religion and politics that they can't be discussed on a meaningless arena like this. Have you read the trash on this so called Off topic Forum? May your God go with you.
