Even if the prophesied "red wave" had actually occurred, our democracy was still safe. I know, many people, mostly Democrats, lied to you that our democracy was in danger. It wasn't, it isn't, and there is little sign it will be in the foreseeable future.
With the caveat that our governmental form is not, technically, a "democracy" but a representative republic, we'd need to see more than a pack of unarmed yahoos misbehaving at the capitol for our governmental form to be endangered. We'd also need to see more than the orderly changing of nameplates on Congressional offices.
What truly was at risk was "rule by Democrats;" which is not the definition of "democracy" even if Democrats would ask you to believe it is.
