"Mom, he punched me back after I sucker-punched him!"
Nobody would have cared about Texas' gerrymandering except for Trump (stupidly) called for it - pretty much every political party has done it in their state over the years, but it's generally been gently putting their finger on the scale. But now that someone that half of the country have been convinced is literally Hitler had a part in it they feel like they can go absolutely wild with it. Everyone should be mad when gerrymandering happens, whether it helps your side or not. Representatives that feel absolutely secure in their seats are bad at their jobs, whether they're on your side or not. Going so hogwild in 'retribution' isn't virtuous.
I'm not defending what was done in Texas. Gerrymandering is gross. But I do hate how the discourse seems to be that Texas started it. They absolutely didn't. Neither party can be blamed for that, and this tit and tat back and forth is the wrong way to deal with it - so are so called "nonpartisan" committees, by the way. It's easy for a nonpartisan committee to quickly become quite partisan. What I wish would have happened is that there was a real dialogue about better fixes for the problem, but instead it became political mudslinging.
Easy part solution - put mathematical limits on the geometry. It wouldn't eliminate gerrymandering but it would certainly help.
Democrats are finally waking up to this, I think, given the recent retaliatory gerrymandering in CA and VA.
