That's literally the point. Because of reactions like yours (specifically that last line re-paraphrasing), anyone on the conservative spectrum is now afraid to express their opinions or reveal such information
No one is asking you to sit quietly. Your welcome to disagree. We expect the conservative to be able to hear about your approval (from their perspective) of the violent murder of babies for your personal convenience without losing their ability to work with you effectively as a co-worker and treat you with dignity while disagreeing. It's fair to think there'd be reciprocity and you should be able to do the same when they discuss gay marriage.
Usually when I point the above out, I'm told that OF COURSE it's cool to expect the conservative to handle talk of abortion or public approval of abortions "appropriately" in the workplace because their perspective it's murder is merely an opinion---and a wrong one at that. But your perspective that gay marriage is not a sin is a FACT, not an opinion, so they should suck it up and keep their filthy biases to themselves.
Unsurprisingly, conservatives do not appreciate the attitude that their opinions are wrong and should be hidden as shameful secrets and liberal opinions are right and should be trumpeted from the roof.
Sorry about the misunderstanding :)
One of the pieces of evidence that this article cites is a video published by Breitbart, a self-proclaimed conservative website that was known to actively seek out, publish, and promote the work of neo-Nazis and white supremacists.
So it's not really so much, "because of reactions like [GP's]", but because a number of "conservative" outlets have been revealed to be outright white supremacist propaganda, and people who are conservative and not white supremacists have done relatively little[0] to distance themselves from them, on the whole.
[0] that's putting it generously
Bernie Sanders was an outspoken champion of Venezuela and its brand of Socialism. Then he mysteriously (ha) went entirely silent on the matter. What shall we do to hold him accountable for his grotesque beliefs, which are every bit as bad in historical application as white supremacy and fascism?
Obama openly championed Marxist ideology when he was younger. Marxism has resulted in the deaths of tens of millions of people in the past century and the brutal enslavement of entire nations for decades. Then Obama got elected President, the left media could not have cared less about his past ideology (and or cheered it on).
How is being a Communist better than being a Nazi in any objective historical comparison? Why is it ok for Antifa to smash skulls, routinely threaten and apply violence, wave the Soviet flag and threaten journalists, march around clad in black body armor, but the world explodes about Charlottesville. Both are quite horrible, the liberal media only cares about one of them.
There's only one explanation for it: arbitrary left wing bias, which entirely disregards history and facts.
When does the aggressive censorship campaign begin for the NY Times? Should they be banned from Twitter?
NY Times: Support some policy -> Policy could be considered related to communism -> Communist regimes have killed many people throughout history
Breitbart: Support hatred and rejection of broad groups of people directly.
Further, Breitbart and similar seem much more willing to engage in propaganda rhetoric and purposeful deceit.
