In reality are there any “bad cops?” Yes, of course. And the reality is “yes” pretty much in any career field there are “bad apples.” So in reality does that make the majority of cops bad? No, it doesn’t and in fact, most of them are good. So in reality there are hypocrites in every church yet in reality that doesn’t make the majority of Christians hypocrites.
If you mistrust all cops because you ran into a bad cop you are incorrect in your inner assessment that all cops are bad. Likewise if you run into a bonafide Christian hypocrite you are also incorrect in your inner assessment that all Christians are hypocrites.
