What matters is what effect the words have today.
That is not the case. The case it that people are choosing to be offended by these things, when there clearly is no intent at offence and you have to jump through a whole multiverse-worth of intellectual hoops to even begin to try and claim it's actually offensive.
It's like when people get offended at the word "Niggardly" which, of course, has nothing to do whatsoever with the word "Nigger" and it's historical abusive connotations. Or those who will get offended because I used "Nigger" even though clearly not in any context that could rightly be claimed to be offensive.
Citing etymology at this point is really calculated to arouse suspicions that you're looking for reasons not to do the right thing.
The "right thing" is not to pander to the whims of the PC scum who are constantly trying to drive wedges in between people. These people have nothing better to do than to try and sew discord by claiming that once perfectly acceptable and descriptive language is now a bad thing.
The sooner we are rid of the PC-types the sooner we can all get back to working to stress-free good lives for all. While PC remains, this world must be a place of division, stress and resentment - because as soon as a word become acceptable to describe a group of people the foul PC scum make it out to be an unforgivable insult to use said word to describe said group.
The PC nonsense is wrecking lives and needs to stop. It has gone on far to long.
