If you don't vote for any reason then you don't have a vote. If you don't vote against the enemy of your ideology, your are abetting them. If you let your principls trump politics, you will likely end up to be a principled runner-up (as in loser). Your opponents prefer a loser, principled or otherwise, patriotic or otherwise, with a sense of duty or otherwise.
As for me, I never have knowingly voted for my enemy, and that includes the Republicans who support the aforementioned legislation, while there was a choice to be made. If you have, then you have abbetted them in the destruction of respect for the Constitution and the principles that built this nation. We will never recover that respect by casting our votes for others who have shown no or insufficient reverence for the Constitution. I'd prefer we face the wolf if we know who he is, rather than face the wolf in sheep's clothing. The latter case is more dangerous, because it is just as deadly, but it is more liable to sneak up closer before it strikes, and we don't see it coming.
