Like this:
often capitalized : a political philosophy, movement, or regime (as that of the Fascisti) that exalts nation and often race above the individual and that stands for a centralized autocratic government headed by a dictatorial leader, severe economic and social regimentation,
and forcible suppression of opposition

Which conflicts with:
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof;
or abridging the freedom of speech, or of the press;
or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
Peaceably assemble, consider the Civil rights marches, King wasn't out there throwing fire bombs at police. But all this waving foreign flags, burning the US flag, riots in the street, disrupting peaceful rallies, that falls under the definition of fascism by it's very tactics.
