MN will probably refer you to the "talk guidelines".
However, these are not uniformly applied. I've had posts deleted on other threads for using certain terms, but I've seen other posters use those same terms and the posts are still there now. I am very glad that they remain, by the way.
There is no consistency. Also, the terms I am referring to are factually correct. Some trans people use them. MN is therefore saying they know better than trans people how trans people want to be referred to.
