both parties do this -- specifically, the one and only green party assembly member in California 1990s was doxxed and infiltrated, while getting congratulatory letters from GOP reps.
The bad thing we are talking about right now is the Republican Party trying to engineer a de facto one-party state through gerrymandering, court stacking, and just taking advantage of the ever-increasing "handicap" both the Electoral College and the two-Senators-per-state apportionment give Republicans due to the rural vs. urban alignment between the two parties. The argument "yes, but the Democrats would do the same thing if they were in the position to" may be true, but it's not a reason not to do something about the Republicans actually doing it right now.
So, yes. It is very much not the same thing. The Republican efforts behind a "voting security" banner, when Republicans in charge of the 2020 vote called it "the most secure ever", is nakedly trying to disenfranchise the vote to tip power in their favor despite the majority of eligible voters going the other way.
