All I'm going to say is that we, as trans people, have been shunned by society for many years in the past and still are in the present. Many people look down on us, many friends and family members would abandon us knowing our trans status, and many people think we are "unnatural" and "disgusting". Knowing that, we should be respectful of everyone who, like us, has been unfairly shunned by society because of their preferences and their feelings. I find homophobia highly insulting, and it hits far too close to home. Many trans people are straight, yes, but in the 1970s, gay people were looked down upon as we are today, although we still don't suffer at society's hand the way they did. In fact, they put down the foundation for a more tolerant and accepting society. Without the gay community, we would surely be accepted in society even less. We live in a large and multifaceted world, and every individual has their own story. Why be so concerned about what other people are feeling, when their feelings don't hurt anyone? In my opinion, a trans person being homophobic is absolutely unacceptable, because there is a lot of transphobia in our world, and believe me, we are not that different after all.
After all, we are both in search of truth. Homosexuals, just like transsexuals, are simply seeking personal integrity and truth. That is one of the bravest and most commendable of things.
