People are pissed about the political situation in the US (imo for good reason).
Rolling up and immediately accusing people (who are imo righteously angry) of being paid shills sounds eerily similar to the bus full of paid protestors disingenuous dog whistle bullshit the right wing media uses to discredit and derail discussions about important matters.
Man have you ever considered that the majority of online discussion boards are against Trump because the majority of people are actually against Trump?
