I used to catcall people while I would drive around town
Why would you catcall while driving around town?
I think it's funny.
Although you may think it is harmless, catcalling someone can really harm someone. It can make them feel objectified and uncomfortable. You shouldn't do it anymore, and you should apologize to the people you've done it to.
I'm not going to apologize because they are allowed to look at me.
Well you should at least not catcall anymore, the majority of women feel uncomfortable when men do that.
