He who argues with a fool is twice a fool, LePaul.
You do not have to justify what you are doing to anyone. It's your time and money.
If accused, do not deny anything. In fact, agree to what they are saying and ask "what are you going to do about it"? Then tell them to get lost and squelch them.
If someone has to log-off in disgust, why should it be you?
Of course I am talking about jerks. The decent guys usually can make you see, if not agree with, their point and respect your choices.
