Is the problem that they are blocking the simple stuff or that they are blocking the major stuff? Your argument seems to confuse the two.

The filibuster is designed so that an ambitious agenda cannot be passed without a super majority. So if you have an aggressive agenda you need to either get a super majority at the ballot box or figure out how to win some support from the other party. The dems failed to do the first and seem to be offended that they are expected to do the second. The filibuster was designed to keep the majority party from blocking out the minority and to keep major changes to our government and society from being enacted without widespread support.

When the filibuster was being used to block Bush nominees for even minor offices the dems were fine with it but now that the table is turned we have Biden telling us the constitution has been turned on its head. Which I find ironic considering the fact that the constitution was designed to limit the growth and power of the federal government and to limit how involved they could be in people's every day life.

Despite campaign promises the dems have done nothing to dampen the partisan atmosphere in Washington, in fact they have done the opposite, now they are paying the cost. America does not want to be a single party country.
