The Arabs were the subject of one of the most bizarre Scottish Premier League matches of the season when they had three men sent off and 'Gers received three penalties from referee Willy Collum.
Houston felt that the decisions of the match official were farcical and questioned the state of the game today after his side were reduced to eight men.
"Where do you start? What is the game coming to?" he asked.
"There were three red cards and, if I thought the discipline was poor here at Dundee United, I would be reacting to that.
"But I was proud of the Dundee United players for the way they tried to play tonight but when you lose a second and third man, it's down to damage limitation.
"I'm disappointed with the fact that the game, in my opinion, is becoming a bit of a farce if those are straight reds.
"There is no point speaking to the ref because they will all get round together and say, by the letter of the law, it's a straight red," he added.
"I just fear for driving punters away if we are getting down to a farcical situation with three players sent off. They might technically be right but they are spoiling the game.
"Was there a tackle in the game tonight? That's what we need to ask. To come out of that game with three players sent off, I worry about the game.
"Would you pay good money for players to be red-carded for such simple offences? Two of them, the second and third, I don't think were red cards. The first one could have been."
