Wow. I mean, talk about living in glass houses.
How about talking about definitive actions in history. That is, things that a given party explicitly supported:
Slavery - Democrats were the party of slavery.
Undermining the Civil War - During the civil war, northern Democrats unsuccessfully urged an end in the fighting - a two-state solution
The income tax - The Democrats were the ones who we can thank for this.
World War I - Thanks to Wilson, hundreds of thousands of Americans died for no particular reason.
Massive taxation - For decades, the most productive Americans had the vast majority of their earnings taxed away by Democrats
Communism - at best, you can say the Demcorats were far more..sympathetic to Communism than Socialism (Democrats love calling people Nazis because to them, that's an insult but never seem to consider calling someone a Communist an insult).
Segregation - Democrats were the ones in favor of segratation. It was Eisenhower, a Republican, who had to send in troops into Little Rock to enforce integration.
The Vietnam War - if you think the Iraq War is a bad thing, thank the Democrats for getting the US into the biggest and most expensive quagmire ever. Over 60,000 Americans died with nothing to show for it.
Iran - We can thank Jimmy Carter in particular for the mess we have with Iran today.
Next to these explicit events that the Democrats either directly caused or explicitly supported the ambiguous and petty list you have in your post seems silly. I mean really, blaming the Challenger disaster on the Republicans? That's like blaming the weather on Republicans (oh wait, Democrats already blame the weather on Republicans).
Many of the other things in your list are really a stretch (either not bad - like the first gulf war) or just an exmaple of stupid government that has nothing to do with party (Katrina relief).
The Republicans aren't perfect but anyone with even a casual grasp of history can see that the Democrats, by far, have a long track record of being on the wrong side of history.
