If you thought everyone in the LGBT community wanted gay marriage, you would be wrong. It's much more nuanced than that.

A new chart from Pew, based on 2013 data, shows that 7 percent of LGBT Americans said they oppose same-sex marriage. And another 18 percent said they favor it, but that they didn't feel strongly.

Perhaps most striking, 39 percent of the LGBT community said the marriage fight was taking focus off other issues of import to them.

Opposition to gay marriage in the LGBT community, such as it exists, is driven by three groups: LGBT blacks, LGBT Republicans, and bisexual Americans.

While 12 percent of the black LGBT community opposed gay marriage, nearly one in five (19 percent) Republicans did, too. Only 45 percent of LGBT Republicans said they strongly favored gay marriage -- the lowest of any group. Fifty-eight percent of LGBT blacks said they strongly favor it.

And the bisexual community was more likely to oppose (8 percent) or not feel strongly about gay marriage (22 percent), compared with gay men and women. Bisexuals comprise 40 percent of the LGBT community -- larger than both gay men and lesbians.

Just 2 percent of lesbians opposed gay marriage, while 4 percent of gay men did.
