Since when is it irresponsible to have an opinion

The CNN site has an article about the Whitehouse claiming that critisizing the war is somehow "irresponsible".

Let's see what our friends at Dictionary.com have to say about the word "irresponsible"

ir·re·spon·si·ble adj.

1. Marked by a lack of responsibility: irresponsible accusations.
2. Lacking a sense of responsibility; unreliable or untrustworthy.
3. Law. Not mentally or financially fit to assume responsibility.
4. Not liable to be called to account by a higher authority.

Hmm. Numbers 2 and 3 seem to explicitly refer to the Bush administration, so those can't be what the Whitehouse is referring to. Number 4 doesn't seem to fit either, given Bush's interpretation of the presidency as a "faith-based initiative". That leaves only the first item on the list: "Marked by a lack of responsibility". Just to be clear here, Mr. President: Somehow it's not irresponsible to mislead a nation to war, destroy a soverign government with no plan to rebuild the nation and toss high-dollar contracts to cronies, yet it IS irresponsible to ask questions about how things were done and what our plan should be?

Sir, I beg to differ.

I would hold forth that the ONLY responsible thing to do in this (or any other, really) case is to ask questions. These decisions are too important, with too many implications for families (American and Iraqi, I might point out), the economy and our safety for congress to simply rubber-stamp your choices. We tried that before, right after 9-11. If you'll recall, that's how we got in this mess to start with. If more Senators had asked more questions and insisted on direct answers, we'd be in much better shape today.
