Ahead of the clash at Molineux reports had quoted McCarthy - whose side are 19th in the Barclays Premier League - as describing people who used internet message boards and radio phone-ins as "numpties".
"I haven't seen the newspapers, but somebody rang me (on Saturday morning) and said an article said that I'd had a go at the fans," McCarthy said. "I would never have a go at the fans."
He added: "I have had such great support from everybody at the club, so I said I never take any notice of internet bloggers, radio phone-ins, or anything else. I said I think anybody who writes on one or rings in to one are numpties."
Although the result did not change Wolves' lowly position in the table, McCarthy's team cut the gap between themselves and safety to three points and will take confidence from halting their recent four-match losing run in satisfying style.
Wanderers went 1-0 up thanks to Kevin Foley's goal five minutes into the second half before efforts from Darren Bent and Danny Welbeck put Sunderland in the driving seat. Stephen Hunt then drew things level and fellow substitute, Sylvan Ebanks-Blake, lashed home a dramatic winner with a minute of normal time remaining.
McCarthy's opposite number Steve Bruce lamented Sunderland's defensive display, branding the concession of three goals against the midlands outfit a "sacrilege".
The Black Cats were without injured central defensive duo Michael Turner and Titus Bramble and Bruce feels his side - who have gone unbeaten in this campaign against all of the teams that finished in last season's top 10 - must improve at the back if they are to avoid a similar mid-term slump to that which they suffered in 2009-10.
"To be fair, the goals kicked us into life and every time we went forward we looked as if we were going to score for a while there," Bruce said.
"But if we defend like that, then it is going to be a tough winter for us again because defensively, individual mistakes have cost us the game. Obviously we were without Turner and Bramble and it showed."
