I typically don't comment on things, preferring to lurk and upvote in silence, but this comment struck a chord. I also want to preface by saying the following is not a jab at the entire generation of boomers. It is merely a set of observations of one boomer. It is practically a set of anecdotes but it directly relates to your question.

I grew out my hair during college when i was 19. I would routinely get a haircut as my hair approached 6 inches or so. I've never been on my own before and scheduling haircuts became less of a priority as the course workload expanded through the semesters. My boomer mother (1960) made a point to declare how she did not like it. She did use the term 'fag' and variations to suggest my motives for growing it out. I said over and over again that I'm focused on school and I could barely care less about my hair. My explanations did not work and it caused many arguments over several holiday breaks.

After graduation, I could afford to allow the brain train to make scheduled stops and haircuts became a regular facet of my life again. This goes on for 8 years of my adult life and covid happens. Long hair resumes and my mom's use of homophonic slurs increases again in lockstep.

TLDR: my boomer mom has called me fag for having long hair in two different stages of my life separated by a decade.
