It’s about “men like you”.
Now, I also find this categorisation vague and unhelpfully antagonistic. I can only interpret it (and MY may correct) as meaning something like “men who are particularly vocal about how women should not feel threatened by the widening of legislation to encompass those born male”. This, or whatever else MY means, may or may not be an appropriate descriptor of you personally. Either way, however, that doesn’t affect MY’s statement about their impressions of how men who do fall into this category will behave given a change in circumstances.
As personal as it may feel to be lumped into whatever the category is MY is referring to, basically, the statement is not actually making a prediction about what you, personally, will do given any future theoretical backlash.
