The anti-Trump Weekly Standard (TWS) is calling for social media outlets like Facebook and YouTube to expand their blacklists of people and organizations like Alex Jones and Infowars.
So, as you can see, Last and the TWS actually have no guiding moral or free speech principles — other than to cheer on and encourage Big Tech Monopolies to silence Trump supporters.
The nub of their argument was that privately held businesses ought to be allowed to refuse certain kinds of services to certain customers, provided that (1) the refusal was based on reasonable, non-discriminatory grounds and that (2) the person being refused had reasonable recourse to an alternative remedy.
The distinction here — and this is important — is that this same-sex couple demanded this cake artist PARTICIPATE in their behavior, that he PARTICIPATE in their gay wedding, PARTICIPATE in what this baker sees (accurately) as the sacramentalization of a sin.
But as you can see from the examples above, TWS and Last only defend speech they agree with, while they cheer on and encourage the corporate censorship of speech they do not agree with — speech that competes with them in the arena of ideas.
