If the framers of the Constitution thought it was an imperfect document why do right-wingers criticize anybody?

Not imperfect in its intention -- imperfect in its restriction.

Rascals will always try to circumvent restrictions on their ambition.

"I see, and with the deepest affliction, the rapid strides with which the federal branch of our government is advancing towards the usurpation of all the rights reserved to the States, and the consolidation in itself of all powers, foreign and domestic; and that, too, by constructions which, if legitimate, leave no limits to their power. It is but too evident that the three ruling branches of the Federal government are in combination to strip their colleagues, the State authorities, of the powers reserved by them, and to exercise themselves all functions foreign and domestic." --Thomas Jefferson to William Branch Giles, 1825

It's a contract between the pre-existing states and the new federal government given new federalist powers in 1787. It cannot be changed without permission of the states and no one, not even the Supreme Court, has the right to "reinterpret" it. It is modified only by permission of three quarters of the states since they are the other party in the contract. The Bill of Rights was demanded by anti-Federalist farmers and tradesmen who didn't trust Hamilton's Federalist Party dominated by bankers and merchants. That codicil guaranteed citizens rights. It included their right to military arms for fighting with or against the formal militia the Federalists wanted to protect their businesses from rebellions like Shays was against Massachusetts banks. PS: The slave owners wanted their slaves to count fully in the census but Northern Federalist English descendants didn't want that because the southern Scots-Irish would dominate congress then. More freemen were in the North and the Federalist commercial interests would dominate if they weren't counted. Even at a 3/5 count the Federalists initially dominated until 1800 when the Democratic-Republican (now called just Democrat) farmers and tradesmen took control. They kept it until the Civil War took it from them and gave it back to the bankers and merchants in the newly formed Republican Party.

You're misinterpreting the meaning of what was said.... Compromises had to be made to ensure ratification of the constitution because the anti-federalists wanted an explicit bill of rights. The federalists insisted that all rights were already guaranteed by the stand-alone document. Naturally, you're not expecting that anybody here knows that.

It's compromise. You give and you take. You may not agree with everything in there (hence the term imperfect in respect to that person's opinion), but as a whole it works to appease the majority of people on both sides of ideological beliefs.

we are critical of left wingers who try to take away rights in the consititution or add rights at the expense of other rights, in other words LIBERALS are L00NY!

Do you know anything about American history?

The Constitution is to be amended when changes need to be made NOT discarded!

we only criticize people who think that each and every part is imperfect

Because they think that we violate it when we... uh.... uh.... IDK, but they do it themselves when they try to make religious laws and vote against gay rights, etc...

Then change it, not violate it.
