I've remarked to others that the halcyon days of "comity" were likely so because the vast majority of legislators were decently well-off white dudes who regardless of the strengths of their convictions, at no point were having to face their colleagues trying to legislate them out of existence.

Now Congress is much more representative (not fully there yet, of course), so fucking YEAH it's more personal and contentious when a fair fraction are being called groomers, or having their bodily autonomy violated, etc.
