跟现在的现实相似度好像非常高,该有的一些主要元素(病毒源于蝙蝠,respiratory
传染,连大家抢sanitizer)电影都有了。电影里的mortality rate是1%,可能只是个

But Just was just the beginning of the White House’s marriage headache. By Wednesday, Ken Mehlman — former Republican National Committee chair, Bush-Cheney campaign manager, and a virtual mastermind of the conservative movement — flipped the partisan marriage equation on its head, making Obama’s bumbling look downright backward.
While much of the LGBT movement understandably rehashed Mehlman’s involvement in propagating antigay hatred during his GOP reign, what seems to have been missed was the

There is an extant myth, propagated by the Christian Right, that homosexuals
engage in highly promiscuous behavior. Granted, there are some homosexuals
that do engage in such behavior. But there are heterosexuals that do the sam

that causes people to ignore heterosexual flaws while highlighting homosexu

篇Why Are There Gay Women?
http://www.lifeslittlemysteries.com/2563-gay-women.html
Straight women are much more likely to get themselves knocked up than gay
women. So, in terms of evolution, they would seem to have a much better
chance of passing on their genes, while at the same time it would seem that
the genes that make women gay would quickly vanish from the gene pool. This
raises the question, why are there gay women?

If you read through all the reports by major western newspapers on the riot,
you will find that they express little sympathy towards the innocent Han
Chinese that were killed. Rather, they spend a lot of time subtly or un-
subtly accusing China of its "repressive" policies in Xinjiang. In addition,
Western reports give disproportionate credit to the opinions expressed by
Uighurs living overseas as political refugees.
Therefore, Western media are propagating sympathies
