I think it's quite political.
After reading the survey again , it is no more political then about the climate or about religion or about race or gender as it is also mention these groups in the survey where it says -
"Similar stories play out with other groups like Muslims and climate activists."
or
"the group that Britons are most likely to say aren't treated in the same way by the police are black people"

If this subject is political then pretty much any subject can be political as politics are so intertwine in everyday life.
