Demographics in Psychology and Social Science studies

With the Cleveland Indians name change making news today, I was looking up the polling and statistics done on the issue. Like I remembered, past polls had shown the majority of Indians didn't find the names of the Cleveland Indians or Washington Redskins offensive:
>In an April 2013 poll by AP-GfK, 79 percent (of natives) responded that the name should not change, 11 percent said it should change, 8 percent had no opinion and 2 percent did not answer.
>A June 2014 poll by Rasmussen Reports found 60 percent agreed that the name should not change, 26 percent that it should change, and 14 percent were undecided. In 2018 journalists for the Associated Press questioned Rasmussen's methodology.
>A poll conducted by Langer Research for ESPN's "Outside the Lines" in September 2014 found 71 percent in favor of keeping the name, and 23 percent thinking the name should be changed.
>The 2016 annual NFL poll found 64% of NFL fans favored keeping the name while 25% supported changing it.
>In May 2016, The Washington Post (WaPo) released a poll of self-identified Native Americans that produced the same results as the 2004 Annenberg poll, that 90% of the 504 respondents were "not bothered" by the team's name

Despite these past public opinion polls/studies, a new study from Michigan and Berkeley was published in 2020 which appeared to completely invalidate these findings:
>...The researchers found that 49% of self-identified Native Americans found the Washington Redskins name offensive, 38% found it not offensive, and 1% were indifferent.
My bullshit alarms were raised, so I read the study itself and found their demographics:
>Gender Cisgender men: 31%
>Cisgender women; transgender, nonbinary, and genderqueer people: 69%

Can someone explain to me how this huge of a gender imbalance is acceptable for a public opinion study? This sounds like statistical manipulation and complete bullshit made to confirm the researcher's hypothesis.
