The poll you refer to without linking it is from July 2021 and the ONE question asked is if people find it "important" or "not important" and most answered with they don't care. Does don't care imply to you that people are against it? Because you can ask the question in a poll and then come and refer to it as gospel otherwise I don't care.
How do you know which poll I am referring to? Actually I said "polls" and there have been several polls at least this year. For instance one in May where the majority of people (65%) where against gender-neutral words. Interestingly a poll made by the the same institute (Infratest Dimap) the year before had only 56% against gender-neutral words. So I conclude the opposition is growing.
