I completely understand why some don't appreciate Halloween. I get it, to each their own right?
However, forcing an entire school full of kids to NOT dress up, because you don't like what they wear, is horseshit. I get some parents don't like Halloween. They don't like blood and gore. That's fine, it's your choice.
But don't push your disgust onto other people. it's the one time of year where kids can actually have fun! Now some schools are wanting to take this away. All because some parents couldn't stand some of the costumes.
Fine. Tell kids not to bring blood and gore to school. I get that. But don't ruin a day of fun, because YOU can't handle it.
