Why do a lot of mass shootings happen every time we have a Democrat as president ?

That's a fallacy!

Same thing with the economy deficit national security and everything. The Republican President FFFFFFkkkkk  things up exponentially and it all unravels and the people are in despair by the time the Democrat comes in.  Then he fixes things, Republicans lie and cheat their way to power again and the process repeats itself.

Because all the Trump Insurrection Party mass shooters out there know they’re on borrowed time because the new Democratic president is going to reinstate all the anti-gun laws  that the outgoing Republican president rolled back. So they figure they might as well commit as many mass shootings as they can until the Democrats have a chance to push through legislation, which Biden is already in the process of doing, even though his trumpublican counterparts will do everything they can to block his efforts to prevent more Americans from getting murdered. The GOP is the Party of Death, after all. They enjoy seeing Americans get murdered. Especially the financially struggling, the Democrats, elderly poor, all liberals, all blacks, etc.  They even call Mitch McConnell “The Grim Reaper”. He’s into it. His philosophy is if you can’t kill ‘em by taking away their social programs you kill ‘em by letting Trump’s Terror Brigade  have more guns. Many roads lead to Rome. 

Because there is absolutely no organization within the democratic party.  Come & visit a blue state & you will agree exactly what I'm saying. 

Frustrated republicans looking to vent.

its ok , biden will do nothing about them anyway .

A better question is why does your country love your toys  of death so much?  In one 2017 study published in Time magazine by criminologist Adam Lankford, it was estimated that 31% of public mass shootings occur in the US, although it has only 5% of the world's population. For every 100 citizens the US has 120.5 guns, no other country even comes close. But who needs gun control? Firearms are the second leading cause of death among American children and adolescents, after car crashes. Firearm deaths occur at a rate more than three times higher than drownings. Now isn't that something to be proud of? 

Instead of making it a political partisanship issue why don't people in your  country demand better gun control laws? Or do they not care about their people, especially their children? Pathetic.

We need to redefine what a mass shooting is.

Let's raise the number to say 20 or more and within 15 min time frame.

Anything less is just a shooting or going postal.

Mass shootings happen regardless of who is president BUT they see more frequent when Democrats are ruining er I mean running the show.

History:In 1865, a Democrat shot and killed Abraham Lincoln, President of the United States.In 1881, a left wing radical Democrat shot James Garfield, President of the United States who later died from the wound.In 1975, a left wing radical Democrat fired shots at Gerald Ford, President of the United States.In 1983, a registered Democrat shot and wounded Ronald Reagan, President of the United States.In 1984, James Hubert, a disgruntled Democrat, shot and killed 22 people in a McDonalds restaurant.In 1986, Patrick Sherrill, a disgruntled Democrat, shot and killed 15 people in an Oklahoma post office.In Sept 2013, an angry Democrat shot 12 at a Navy ship yard.

Nearly every mass shooting was done by a Democrat or non Republican.

Clearly, there is a problem with Democrats and guns.

SOLUTION: Let’s make it illegal for Democrats to own guns.

The above list is a little old, but you get the point.

And the Vegas shooter was a DEMOCRAT.

Gun crime was up 20% in 2020. Who was president then, I forget?

George Carlin said it best, it's a big club and you ain't in it, he was talking about both fraudulent political parties
