A majority of Americans support Jason Collins' decision to come out gay and a range of gay rights issues.

According to an ABC News/Washington Post poll conducted by Langer Research Associates and released Thursday, 68 percent of respondents support Collins' decision to come out gay on the cover of Sports Illustrated, making him the U.S.'s first openly gay professional athlete.

Pollsters also asked about the Boy Scouts of America's (BSA) proposal to partially end its gay ban. Under the plan, set to be voted on later this month, gay scouts younger than 18 would be permitted but adults would continue to be banned.

Sixty-three percent said they support allowing gay scouts, while 56 percent said they oppose the organization's plan to continue to ban gay adults.

A majority (55%) of respondents also said they support allowing gay and lesbian couples to marry.

A majority of Republicans (52%) and conservatives (54%) support Collins' coming out, while 53 percent of Republicans support admitting gay scouts.

Democrats support gay rights in greater numbers. Eighty-one percent support Collins, and 70 percent marriage equality. Sixty-eight percent disagree with a ban on gay Boy Scout leaders, while 70 percent support allowing gay scouts.
