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.
A screech is a high pitched sound, nothing more unless otherwise indicated.
It'd be really cool if someone familiar with what I'm linking to below could comment, especially regarding the word screech and its related forms!
