When the Dims make claims of voter suppression what specifically are they talking about?

I've yet to hear a sensical explanation of exactly what the Dims are whining about when they say conservatives are suppressing Dim voters. I know Pelosi was pushing HR1 long before the Covid-19 pandemic and now Dims are trying to use the completely jacked up election of 2020 as a reason to pass HR1 legislation, they're saying mass mail in voting increases voter turnout and they claim every American should have their vote counted. So who's preventing any legal voter the right to vote? And yes, I believe people should understand it's their civic duty to go in person and vote legally with verifiable identification, who would be against that?

The question is do we really want every American to vote, particularly when one party (the Dim party) is essentially offering government giveaways and entitlements to lure voters? Seriously, as Margaret Thatcher so famously said, "Socialism is great until you run out of other peoples money." Hey, with the passage of HR1 that's exactly where we will find America in a few years when +60% of Americans are voting for that big titty mama government, we're already out of control with funny money being conjured into existence by the trillions. I guess the leftists want to finish the country off with an elaborate ballot harvesting scheme, that's really what HR1 is, a mass mail in ballot harvesting scheme and the Dims know once they get that legislation passed they're on cruise control.

In the meantime EO Joe is going to attempt to enact a EO that's going to allow ballot harvesting/mass mail in voting because they know a shite ton of Dims are unmotivated and they will not get out and vote in person but if the Dim machine can get a ballot to the door of their unmotivated constituents and allow weeks for those individuals to put down their blunt, Cheetos, Dr Pepper and Play Station they're going to get millions of votes they ordinarily wouldn't get. Are these the voters we want shaping the future of America?
