The Donald is NOT an alt-right subreddit. Yes, many "alt-right people" spend time and post there but it's a mix of different political thoughts. Heck, even some Freepers who don't understand what the alt-right is post and lurk there.
There IS an alt-right subreddit. It has about 10k posters. In fact, Richard Spencer (who coined the term altright with his prior publication called AltRight) is doing an AMA on Reddit this week.
Taken from the AltRight subreddit:
What is the Alt-Right?
The Alt-Right, unlike the dominant ideology of the 20th Century (Liberalism/Conservatism), examines the world through a lens of realism. Rather than continue to look at the world through the ideological blinders that Liberalism imposes in its dogmatic evangelism of the Equalitarian religion, we prefer to look & examine social relations & demographics from a perspective of what's real. Thus, racial & sexual realism is a key component of the Alt-Right - perhaps the key component that ties the diverse factions within it together.
Another core principle of the Alt-Right is Identitarianism. Identitarianism is the prioritization of social identity, regardless of political persuasion. Thus, the Alt-Right promotes White Identity and White Nationalism.
And if anyone is uncomfortable with that, they simply do NOT care.
This is like a denominational argument. Two groups both claim to be, for example, the only ‘real’ Evangelicals.
The truth is, one group does not get to dictate to the other. The Whiteness group can pout all day that they are the ONLY Alt-righters. It doesn’t make it true. Neither does your contention that some Freepers post at The_Donald mean that the site itself isn’t Alt-right. If an atheist attends a church service, it doesn’t mean the congregation ceases to be Christian.
I spend ~an hour a day on The_Donald. They fully and enthusiastically embrace the designation, Alt-right. It’s who they are. For some reason, you can’t accept that. You want to dictate that only a piddly little identity group can rightfully claim that title.
You don’t have that right or that power. If an energized, dynamic, growing and dedicated group says they are Alt-righters, you’ll simply have to broaden your definition. For example, I don’t deny that your micro-subreddit is Alt-right. Like Paul Watson, I acknowledge the obvious: that there are two types of Alt-righters. One focuses on whiteness and the other doesn’t. You may not like the fact that the group unfocused on whiteness calls itself the Alt-right, but that personal reaction changes nothing.
You have a very narrow, rigid POV. I can’t change it. But there’s something you can’t change, either. It’s the fact that the vast majority of high-energy, passionate and almost uniquely motivated group at The_Donald call themselves the Alt-right. When Paul Watson posted his tweet about the two Alt-rights, The_Donald users couldn’t feature it or upvote it fast enough. He spoke for them. And you don’t.
