im a transgender girl but why is it that many cisgender girls hate me and see me as competition

It's unfortunate that you're experiencing this situation. The feelings and reactions you describe can stem from a variety of factors, including social dynamics, misconceptions about gender identity, and societal pressures. Here are a few points to consider:

1. Misunderstanding and Lack of Awareness: Some cisgender girls may not fully understand transgender identities, leading to misconceptions. Educating others about gender identity can help mitigate these issues.

2. Societal Norms: Society often sets up rigid standards of femininity and womanhood. When someone deviates from these norms, it can cause discomfort among those who strictly adhere to them.

3. Competition and Insecurity: The idea of competition may arise from insecurities. For some, the presence of a transgender girl can challenge their views on gender and beauty, leading to feelings of rivalry rather than solidarity.

4. Cultural Influences: Media representation often plays a significant role in shaping perceptions. Negative portrayals of transgender individuals can contribute to stigma and bias.

5. Interpersonal Relationships: Each individual has their own experiences and perspectives. Some may project their insecurities or fears onto others, influencing their behavior.

Building connections and fostering understanding can be beneficial. Emphasizing shared experiences among women, regardless of their gender identity, can help promote solidarity and reduce conflict. Remember, not everyone feels this way, and many people, including allies, support and embrace diversity in gender identity.
