Please be consistent. Sometimes you reject "female singers" as a translation for "énekesnők" and inset on merely the word, "singers" On other occasions, you require "female singers" as being correct and "singers" is considered a wrong answer. I suggest for "művésznők, színésznők, énekesnők" you accept both gender-specific words such as "women or female singers" and the gender-neutral words, such as artist, actor, and singer.
Yes. There are female actors who object to the word "actress", feeling it diminishes their profession. After all, we don't say doctoress, teacheress, etc. "Stewardesses" are now "flight attendants", "waitresses" are often "servers". I admit to having a bit of trouble remembering to use the newer, gender-neutral words, but I try to call people what they prefer. :)
