As a person living in Turkey, a country with mostly homophobic and transphobic people in it, this game really touched me. I think the main problem with people who act with their hate towards trans and other LGBT people is their incredible lack of empathy. Their primal sense of hate towards a slightest difference. I think games and experiences such as LifeLine are capable of making us feel how it affects LGBT people by putting us in the shoes of these wonderful people who just want to be accepted.
Please never fear while facing the ignorance. Your braveness is encouraging everyone around you.
