A lot of this thread seems to be about prescriptive grammar, meaning "this is the right way to use it", which is just a red-herring for the most part.
Switch to descriptive grammar. That is, what is the phenomena being described? What is the word trying to get across? Focus on the goals of the words, not the words themselves. What are people trying to convey when they say a word, not "what is the actual, proper use of this word, traditionally".
Otherwise you're just avoiding the topic entirely and going around in circles.
Here's a little relevant pro-tip on how to be a proper human: people are people, first and foremost. Highlight the similarities, embrace the differences. realize your fear or discomfort are a you problem, and not a them problem. And when in doubt, ask someone from the group you're curious about. The universe is vast and forever weird. Be comfortable with the fact you do not know how it works, and allow others to change your perception of "normal". Understand there is no end-point; this is a life-long process that never ends.
okay, that's all I have to say for now. stay weird, humans!
