There is no agenda. There have always been trans and iffeminate kids. Previously they were shunned and made fun of, which forced them to hide who they are, or worse. Nowadays most people are accepting and more are understanding their differences, so you're seeing what has always been there, but is now coming out of the shadows.
Save your anger for something that matters. How kids dress and who they love is not your concern.
Gender dysphoria affects a very small percentage of the population, accounting for 0.005–0.014% of the population for biological males and 0.002–0.003% for biological females, according to the Diagnostic and Statistical Manual of Mental Disorders.
This is absolutely part of a bigger agenda.
Also, MOST PEOPLE DO NOT accept men in women's bathrooms, men competing in women's sports, or this disorder being presented to young children as normal behavior within society. Respecting someone and celebrating someone are not the same.
