Mourinho was sent off at Villa Park, along with midfielders Willian and Ramires, by referee Chris Foy as Chelsea lost 1-0 in a blow to their Premier League title chances.
Mourinho later called for the Premier League to consider not appointing Foy for Chelsea matches in future.
Asked if he had spoken to Ramires about the red-card challenge on Villa midfielder Karim El Ahmadi, the Portuguese said: "Don't you have other things to ask about that game more important than Ramires' tackle on minute 92?
"You think that in that game the most important thing was Ramires' tackle in minute 92?
"I don't want to answer, because I feel that what happened on minute 92 was a consequence of the other 92 minutes that we played before that.
"I'm sorry if I'm wrong or if you don't agree with me, but I think if you want to ask you should ask about what made that tackle happen. But that's just my opinion."
Mourinho, who has already been fined £8,000 by the Football Association this season following his touchline dismissal against Cardiff City in October, declined to elaborate on the events in the previous 92 minutes of action at Villa Park.
Asked specifically what he was referring to, he said: "Everything that happened. I bring the game into disrepute. I cannot."
Mourinho was also asked if he expects a reaction from his players following the defeat.
"We cannot have a reaction to Villa Park, because if we have reaction we bring the game into disrepute," he said.
"We just close our mouth and we keep going."
