I'm going to be honest, I can't stand this trend of trying to neutralise everything. I grew up in the 90s/00s so I get this might be a generational difference but to me people being more open about themselves is an amazing thing and I'd hate to see it disappear. I don't really see what's wrong with accepting people are different and embracing it, rather than fruitlessly making everything in life a shade of grey.
Personally I actually view it as being kind of offensive, if I'm honest. Terms like "people of colour" to me come across as people minimising the vast and interesting differences in culture and customs that such a broad term covers.
While it's not "technically" underage rape, let's be honest it basically is. No normal person thinks it's acceptable for some in there 30s to have a relationship with a 16 year old.
The law is there to protect say an 18 year old in collage, where it's common for 16-18 year olds to be in the same classes, not for creepy 30+ year olds.
