What years of Gen Z males started becoming more conservative?

I was born in 03 (class of 2021) , when I was in freshman year in 2017 all upperclassman were very liberal. My grade was about 50/50 liberal/conservative I’d say. However once we became seniors, the freshman (class of 2024) were extremely conservative edgelords and often mocked anything remotely liberal. I’ve heard from underclassman that it’s even worse now, and that there’s like barely any liberal guys specifically in that school. What are your guys experiences with this?
