No revisionist history. Pelosi refused to bring it to the floor because she didn't have the votes. There's lots of stuff to criticize her on, but whipping and vote counting aren't that.
Do you remember 2000 - 2006? We had the Republicans floating and pushing anti-marriage freedom constitutional amendments. They controlled the House, Senate, and White House. Republicans controlled the 107th, 108th, and 109th congresses. So while Pelosi could have proposed the Act, there's no guarantee Hastert (the Republican Speaker) would have even have allowed that on the floor.
Right, if she didn't have the votes, she wouldn't bring it to the floor. Simple as that. She didn't not bring it up because she wasn't supportive of the LGBT+ community.
And bringing up DOMA, which was passed in 1996, at least get your facts straight. Republicans controlled the House when DOMA was passed. Pelosi was not the Democratic leader in the House then; that was Dick Gephart. Yes, Clinton signed it. However, there was much more public support for the bill then.
