My dad is a weirdo and I hate my family

I (m18) use disinfectant spray to use around the house on couches before I sit on them. I don’t like touching everyone else’s germs. It got to a point where my family is stupidly offended about it. Today, after my dad went to the store he claimed I didn’t need it because all I did was hog it and use all of it in a few weeks. It angers me. He’s a weirdo to me, why does he want me to touch his germs? I don’t want his or anyone else in my families germs. The rest of my family is offended about me and agree with him. I hate my family.
