There's nothing "hyperbolic" about it. The party that's in power during redistricting always does this. It so happens that this time around it was the Republicans, and they've set up the districts so that they feel safe in pursuing an unpopular agenda.
The actual hyperbolic conspiracy-theory angle on redistricting is that the long-term plan, funded by the Kochs and others, was to ensure that only the most extreme Republicans are safe, and that moderate Republicans will be in danger of primary challenges from extremists.
Political scientists have long said that there's not a lot of evidence for a change in macro outcomes due to gerrymandering. In most scenarios, if anything, gerrymandering makes sitting politicians on both sides more safe. It's really hard to actually tip the balance such that one side gets significantly more seats because if you spread your supporters out efficiently (51% your party) and then cluster the other party, you get a bunch of weakly held seats. However, if you want safe seats, you get fewer of them.
Esch state draws its own districts, so there were 50 different "party in power" scenarios in 2010. Democrats in California gerrymandered themselves into a super majority. In Texas Republicans drew themselves some very safe districts. But there is no national gerrymandering or "party in power".
