Define select intrusions in your own words please.
Ohhh, I dunno. How about gay marriage for starters? Nearly all the conservatives I know, both personally and on the internet seem to be pretty staunch supporters of the government preventing gay marriage, and preventing equal tax bonuses for gay married/civil union couples.
How about Marijuana and other drug restrictions? Never seen any bigger supporters of the drug war than conservatives. For a non addictive, non destructive drug like marijuana, it's pretty amazing how much they want the government to regulate it.
Patriot Act? How about that nugget of goodness right there? They were completely for it from the beginning and for most of its life, but as it's really starting to become unpopular to extreme levels. But once another president came into power, they were trying to pin everything about it on that guy. And don't even get me started on the shitty fact that Obama extended it.
Abortion. That's one that they've been trying to get the government to restrict for a long time now. They'd love it if they could get their state governments, or better yet the federal government to completely ban abortions.
