First - we need to clear up something. Democrat doesn't always equal Liberal and Republican doesn't always equal conservative. Parties have changed their political ideologies and stances numerous times during their long existance. Just because they are one way now doesn't mean they always were. If we are going to talk Democrats and Republicans - talk that. If we are going to talk conservatives and liberals, lets leave the political parties out of it becuase it is deceptive.
What brought about Love Canal was a lack of any sort of regulation on pollution and it's consequences by corporation and an unwillingness to enforce any sort of accountability on them. Regulation is typically associated with liberals - less regulation with conservatives.
Then you are also being disengenius with your second paragraph.
Some of the most polluted places on earth are in former communist countries.
Some of the least polluted places are in those primarily socialist countries with strong environmental laws and regulations in place.
So what does that say? It says you are being a wee bit deceptive by leaving out a lot of information in an attempt to label it a "liberal" problem.
Communist countries in their headlong rush to industrialize disregarded the environmental and public health repercussions of industrialization. We did the same. Now they are having to face the consequences of this and it's pretty damn grim. The fact that the countries were communist does not mean their every action was "liberal". This is the fallacy.
And what happened to them before the government helped? Mental illness is ugly. It's hard to help them and they have few adorable poster kids. They frequently slipped between the cracks and have seldom been able to support themselves. What exactly would you propose? These - along with the elderly, disabled and children are our most vulnerable citizens. As a civilized nation - don't we have an ethical obligation here?
I'll have to try to address some more of this later but - you're making me type too much. Darn conservative!
