I looked around on Purim and saw nothing inappropriate (except for a kid dressed as an ice-skater, but that was inappropriate on Purim or not). Maybe its just that in Brooklyn most women usually dress in 95% black, that any other color shows up a lot?
Ames, fanatic has multiple connotations – some bad, some good. So when you say “oh no I sound like a fanatic” I assume you are talking about the irrational enthusaism side. Being zealous FOR THE RIGHT REASONS, so long as you recognize not everyone follows the same way, is great! Just be careful not to fall into the other yetzer hara trap. You start being super machmir just to shove it down others throats – this comes with its own sins.
