Feminists on this subreddit are making the following argument: if we use a term or concept that is the reverse of something feminists employ, we must be wrong.

For example, if you say 'gynocentric,' you're just being the male equivalent of a feminist, because they use 'phallocentric.'

So it doesn't matter, for example, if our legal system really does focus on the needs of women to the detriment of men; those who say 'gynocentric' are in error, because the word is too similar to feminist terminology. We need to be more original, if we want to be considered right.

Is there a more formal term for this logical fallacy?
