The home side trudged off at the break with boos ringing round Easter Road after Stuart Armstrong opened the scoring for the Tangerines in the 29th minute.
But, after both sides were reduced to 10 men following red cards for Kevin Thomson and Gavin Gunning issued for an off-the-ball fracas, Hibs rallied to level through Scott Robertson with nine minutes left.
And McNamara hinted he may appeal Gunning's part in the red-card drama if television footage supports the player's claim of innocence.
He said: "I have spoken to Gav and he said he didn't throw a punch. The referee said that they were fighting, so you can take what you can from that.
"I think the two of them adopted an aggressive manner, which merits a yellow card. It changed the game and gave their crowd something to cheer about.
"We lost Gavin then had to put Paul Paton back to right-back when he had been excellent for us in midfield and we lost our way a bit. But it didn't really punish Hibs.
"I'll consider appealing it. We'll look at [the incident]again, I've not had a chance yet. But we appealed one last year that I thought was a stonewaller [that we lost]. It's B£1,000 a time to appeal. It's a lot of money."
