I used to correct typos for people on slashdot, whilst feeling some sort of superiority, but generally it earned me negative karma, and usually didn't address any useful point.

Wikipedia, to summarise, suggests:
Fascism is a radical, authoritarian nationalist ideology. Fascists advocate the creation of a single-party state. Fascist governments forbid and suppress all criticism and opposition to the government.
Following the defeat of the Axis powers in World War II and the publicity surrounding the atrocities committed during the period of fascist governments, the term fascist has been used as a pejorative word.
so sure, a rather lazy evocation of right wing thuggery, but intended as an insulting comment on the present direction of government. personally I prefer Nazi, but Godwin's law, and all that. The adverts suggesting you inform on your neighbours, and the general application of emergency powers to any situation are rather reminiscent of the early German state. If you are scholar of political history, as your post faintly suggests, I would be comforted to hear reasoned arguments that the situation currently bears no resemblance to the past.
