I'm not sure, but I don't think it's Scar. Scar was bad, but he was lazy. He killed Mufasa, sure, but he could have easily killed Simba too, and not even bothering to check if the deed was done hurts his credibility as a villain to me. He had a great plan, but putting his incompetent lackeys in charge of the easiest (and potentially the most satisfying on his part) assassination ever was lame. His plan was evil, but his performance was lazy.
1) Do you think that a Trans gender women has the responsibility of telling their potential partner/suitor of their medical history?
No. They should be comfortable with who they are and disclose that information whenever they see fit with whomever they choose.
2) Would you continue dating them if this fact was established early on in the relationship? Even if you really liked them.
Love's love. If they're comfortable with me enough to trust me with that information, then they're good enough to stick around with.
3) If you were in a long relationship with a trans person and figured out about the op later, what would be your thoughts and what would you do?
There must have been a good enough reason for them not telling me about it. Realistically I would be hurt if they weren't comfortable telling me about it despite the long-term relationship, but it's one of those things that I could probably get over if we loved each other enough.
