Are LGBT themes and characters appropriate topics for a medium many still view as solely for children/teenagers?
Absolutely! Adolescence is a time when most people develop long-lasting belief systems and any prejudices they might have. It’s also a time when LGBT people become more aware that they’re “different” and often feel isolated and alone. Showing this age group LGBT characters in situations they can relate to should help reduce much of the prejudice many LGBT people experience both as youth and later in life.
