EFLImpudence is a pedant, and by their very nature pedants are incapable of considering evolution of new ideas.
What is a pedant person?
one who is unimaginative or who unduly emphasizes minutiae in the presentation or use of knowledge
EFLImpudence does indeed present strawman arguments.
For instance:
The subject was the dumbing down of universities, dismissed by Bobby because he didn't like the author of the article I quoted because he is a bit of a right-winger, despite there being several other people writing similar articles;
I have no personal knowledge of the individual, so to suggest I do not like him is nonsense.
I disagree with his ideology. That is different. It doesn't mean that I do not like him. I would have expected a pedant to know the difference between "not liking" and disagreeing".
To explain why or how it is decided that these things might be wrong, I listed some examples and then an extreme example of someone calling an ant a giraffe. This again was dismissed by Bobby because the word for ant is different in Portuguese
You implied that an ant must always be called an ant. My example illustrated how such a pedantic approach is ridiculous.
The label for an ant is determined by the group of people with whom you associate.
Similarly the meaning of 'wicked', 'far out' and 'fart' is determined by the group of people with whom you associate. Sometimes the meaning of such words can be very different in the various groups.
I can appreciate that to a pedant, that is a difficult concept to understand.
The reason words change meaning is because people misuse them, others copy uncorrected mistakes and it becomes such a commonplace error that the ignorant majority get their way.
That can be one reason, it is not the only reason.
I can appreciate that to a pedant, that is a difficult concept to understand.
If someone mistakenly calls an ant a giraffe, just say "No, you are wrong; that is an ant".
That is a perfectly acceptable practice, if someone makes a mistake, but consider the other reason, which you refused to recognise by ignoring it, why words can adopt a different meaning, simple evolution of language. 'Far out', 'cool', 'awesome', 'fit' and 'wicked' are perfect examples of evolution of language. They did not come into common usage by mistakes. They came into common usage by intentional use of other words.
Indeed, the current British PM uses language in an esoteric way, such as 'bog roll Brexit' and 'chicks'.
