When will we hold the NDP to a higher Standard?

I am glutton for outragous-ness.
From time to time I get a rise out of reading the CBC comments section within their news articles.

As I am sure most readers know;
Our friend NDP MP Pat Martin dropped the "F-Bomb" on a twitter poster pertaining to the Government

He stated:
“This is a f—ing disgrace … closure again. And on the Budget! There’s not a democracy in the world that would tolerate this jackboot s—,”

This is from a Member of Parliament who was elected in 1997, and has been collected a paycheque from the taxpayer for roughly 14 years.

I am not offended by swearing, I do so daily.
However I once again find this situation as the Canadian media not holding the NDP to the same level of scrutiny as the Conservatives or Liberals.

Had John MacKay or Peter Van Loan made similar comments there would be cries from the NDP that they should resign or publicly apologize.

However with the NDP the most common response I get is "Its Pat Martin, what do you expect, he is a spirited guy"

Stockwell Day was a "spirited guy" and I don't think we would have given him the same "meh" reaction had he dropped an F bomb in regards to the Liberals passing legislation in the same manner when they had a majority government.

It appears that the public doesn't quite take the NDP seriously yet;
They still get the treatment as though they are the same 3rd opposition party with 19 seats as they were in 2004.

However if the voting public and the media don't hold them to the same standard, and don't take them as seriously as the Tories and Liberals,

Then I have to ask;
Why should the Conservatives?
