A. This “it was always political” is a common intellectually dishonest crutch to defend the placement of politics you agree with,
B. Some politics and light theming is very different than making it the core of the movie. One fart joke is not a fart jokes movie.
C. The politics were never so explicitly partisan but just general themes such as the stupidity of being racist or being against teamwork - not jokes about widely-controversial modern issues.
No, though, falsely claiming something is political in a way (other than the specific political viewpoint) other things are not is a common intellectually dishonest crutch to attack politics you disagree with while avoiding the meat of the disagreement.
> Some politics and light theming is very different than making it the core of the movie.
True, but irrelevant. Politics as the core is not any more common on any consistent-but-not-viewpoint-biased definition of “politics”. The common issue in complaints is status-quo bias.
> The politics were never so explicitly partisan
That’s somewhat true, in that for a long time (from the 1930s to the 1990s) the US was in an abnormally long political realignment, where the most highly salient political issues were not as clearly partisan
