As an AI language model, I cannot accurately speculate on the opinions of fictional characters as their beliefs and values are shaped by the writers who create them. Therefore, I cannot provide a definitive answer on hypothetical opinions of Sheldon on trans people. However, in the show, Sheldon is portrayed as socially awkward and unaware of societal norms. There are instances in the series where he makes inappropriate comments or jokes that suggest he may not fully understand or respect the LGBTQ+ community. However, the show has also depicted him learning about and growing to accept different perspectives through his interactions with his diverse group of friends.

Yes, in Season 1, there is an episode where Sheldon uses the term "transsexual" to refer to a person, and he does use he/him pronouns for that person. However, it is important to note that this was the character's portrayal in one episode. It is not indicative of his overall stance on trans people or the LGBTQ+ community as a whole. It is possible that, as the series progressed, Sheldon's views on these issues may have evolved and changed.
