My dad wants me to switch Boxing gyms.?

The place you described does not sound like a safe place to be learning a martial art or combat sport. Go down to the kickboxing place and check it out. Maybe you'll end up liking it. Ask the people at the kickboxing academy if they know of any places close by that teach only boxing. Don't try to convince your dad to let you keep going to your current boxing gym. He's probably right about the mold and stuff. Just try out kickboxing, maybe you'll end up liking it as much as boxing. The kickboxing gym might even have boxing coaches.
