Do you believe in the much evidenced phenomenon of social contagion?
I believe there are strict rules for reporting about specific suicides, for example, to avoid copy cat situations.
There are lots of accounts by detransistioners (linked on other threads) about how they were attracted to being trans because they were suddenly seen as cool, they had social capital, people were falling over themselves in schools and healthcare to affirm and listen to them, and they got to have a flag. About belonging, rather than body dysphoria specifically.
Companies such as E45 with their new ad enthusiastically cheer on transistion.
Ofc there is such a thing as grooming which can take lots of forms including extreme political views. This is why we have Prevent training in the UK (government anti extremism training).
None of the positives which relate to trans identity applies to far right views - very few people would give you a positive response to expressing them. You are unlikely to be affirmed and encouraged by your school, GP, therapist, etc.
So no, I don't think your comparison holds.
