@EveryBlinkingDay I'm afraid I was being more than a little flippant
You are not wrong in seeing a person as female if that person is female.
The people who are wrong are those trying to force you, or anyone else, to believe that humans can ever be anything other than biologically male or female. And call you names, or worse, if you don't turn yourself inside out conforming to their demands.
The person in the video insists she is non-binary, which is impossible, since human sex is binary..
If you can do so without real-life consequences such as threats, violence, risk to livelihood, ignore the whole concept of "misgendering". Describe people as you see them. And also, if you can, avoid people with "gender identities".
In circumstances where you can't do the above, keep quiet, avoid the subject, use compelled speech like pronouns and descriptions as little as possible. Read about the subject.
Would be my advice.
