"Screeching" in english (at least North American english) is typically a gendered derogative. You generally wouldn't say a man was "screeching", not unless you also wanted to imply he was effeminate.
By avoiding the word, you avoid insinuating the target's gender is part of the issue, and/or avoid insinuating that the target is effeminate when they "should not" be, i.e. you avoid homophobia.

Screeching is usually associated with high pitched sounds and that is associated with women, to the point men making loud high pitched noises usually gets called "screamed like little girl".
