Even so, there are uncomfortable undertones in comparing those people to neo-Nazis and the like. If you think that radical trans activists are in some meaningful way comparable to neo-Nazis and other violent thugs, or that they are mentally ill, then it may be you who has been taken in by online propaganda.
I guess it annoys me that you left this little ad-hominem in parentheses at the end of your original comment. If you have some kind of issue with trans people or trans rights, you should really just say what that is, rather than making these kinds of comparisons.
