You were doing well right up until the end where you fell back into "attack the Dems" mode.
As to the meat of your post (basically that Dems are worse or more widespread than Libs), I'd say that's pretty well provably false.
Conservatives and religious organizations are constantly trying to enact LAWS banning thought, words and deeds. You will find hundreds of puritanically restrictive morality based legislation on the books (can't buy beer on Sunday, dry Counties, book banning in public liberaries, banning explict lyrics as obscene, banning pornography, banning anal intercourse, banning.
Liberals and anti-religious organizations are constantly trying to enact laws banning thought words and deeds. The left is just as control-hungry and right-wing extremists, and want to shove their agenda down everyone's throats every bit as much.
Your examples of mostly-forgotten, archaic, 19th century laws as representative of conservatism is laughable.
You can't even really marginalize the conservative side of this debate as trivial or minor. This is an article from James Dobson's "Focus on the Family" group organizing political action right now to maintain all of these morality laws that restrict the deeds of consenting adults.

Well, yeah, he speaks for ALL conservatives.
You will find no such attempt an enacting laws banning (for example) the KKK from organizing or sharing their thoughts on StormFront or whatever the website dejour is for such people.
(I bring the KKK into this not to suggest that anyone here is racist, but race issues is a major part of the whole "PC" debate.)
Only because the PC make it part of the debate.
In fact the ACLU appealed the KKK's right to Adopt-a-highway in Missouri back in 2000. There is no more liberal pariah than the ACLU and there is no greater opportunity to for liberals to stand by and allow or actively conduct a "PC-police" effort than this case in point.
My point is this... conservative PC police have had tremendous success in restricting thought, words and deed though enacting laws. Liberals have had tremendous success in winning "the hearts and minds" of people by convincing them that it's in their best interest to conduct themselves in a PC way.
LMAO. One can only assume you actually believe THAT. Liberals have done so well they hold the Presidency, control of Congress, and are the majority in the US Supreme Court. Obviously your "tremendous success" is not reflected by the voters.
If conservatives (specifically religious/moral conservatives) were to take a similar action and focus their efforts at stopping porn on a "hearts and minds" you might be able to argue that conservatives are no worse (and maybe better). But as long as they are out there using the stick (laws) to enact their beliefs rather than the carrot (hearts and minds), you would be wrong.
In any case, no one can at this time accurately assert that the only ones pushing for a return to any form of dark ages are liberals. That's just patently false.
