The first thing that comes to mind of course, is immigration. But liberals have been at this a long time.
Remember when elective abortion was a backroom operation?
When I was a teen, any girls who were silly enough to get pregnant (and this was before the pill) usually went to help out a distant 'aunt' and came home a few months later without that little bulge. Some girls went to stay in homes run by the church, and gave their babies up for adoption. Some girls faced their families with the news, and the babies were accepted and grandparents helped raise the child. Abortions were few and far between, but there were always some who chose the very expensive alternative either because they didn't want their lives disrupted, or their families to find out. Every so often a case would make the papers because the woman died due to the ineptness of the doctor (or hack) performing this procedure.
The cure for this? Why, lets make abortion legal. Since so many women were dying to have abortions, lets make it safe and an everyday affair, no different than having a mole removed, and just as safe. Even better, lets get it covered under our insurance - forget the fact that it's an elective procedure, as very few women wake up pregnant. Just make it a right, and you've just gotten the feminazi vote.
Now we have immigration problems. Rather than use common sense and refuse benefits to illegal persons, the liberal solution is to just let everybody be a citizen. It doesn't matter if you broke the law, or if you could have entered legally after filling out your paperwork and getting in line to immigrate. The rules don't apply when dems are looking at millions of new voters. Of course, the cost to take care of all these people who have not paid into the system will be a little expensive. The days when an immigrant had to have a job, or at least a sponsor who would be responsible for their upkeep, are gone. After all, citizenship is a right for anyone who can break into this country. Now you've gotten the illegal immigrant vote.
Wikipedia: enabling: used in the context of problematic behavior, to signify dysfunctional approaches that are intended to help but in fact may perpetuate a problem. A common theme of enabling in this latter sense is that third parties take responsibility, blame, or make accommodations for a person's harmful conduct. The practical effect is that the person themselves does not have to do so, and is shielded from awareness of the harm it may do, and the need or pressure to change.
Liberals love to take responsibility for all people with destructive or illegal behaviors. Of course, it's the rest of us who get to pay the bill.
