Yeah, you may want to revisit your high horse based on yesterdays reality, or not and keep living in lala land.
First some facts: your event is not about lesbians, it's about being anti trans. There is a reason you stopped spelling it out, as when it happens you were refused license by the city to organize your rallies at all.
Second lesbians, by far and wide, are the most welcoming group of transgender people in general. Survey of dating site showed over 80% approval of such, rising over 90% when it's a trans woman after genital surgery.
That's why when you plan something silly like that for months, you end up with ~10-15 people turning up, because no, it's not actually supported. There were thousands of lesbians just few miles away at the pride event instead, they had the time, they just do not like your transphobia.
But that's the way transphobes work, od a rally once a blue moon, get 10-45 people in, depends on how many you will bus around from around the country, and then make tons of excuses about how "everyone supports us anyway", even though this is repeated and stead pattern.
Also, well, get used to the idea that if you make a transphobic rally, people who do not stand for transphobia will turn up to oppose it. Happens literally every single time, you should know the drill.
