Also, openness and willingness to learn is another thing you can do.
Say, to not write off "feminism" without truly understanding (wanting to) its spectrum of positions [just because you may have bought into the stigma that the label of feminism carries - mostly perpetuated via stereotypes].
If this topic is not of interest enough to learn [which is fair enough, as there's so many interesting things in this world/issues for each of us differently to focus our passions on]....
...but, how about then, at least, refraining from perpetuating the stereotypes of feminism by not partaking in bashing it before truly understanding it? To not be contrary without first allowing critical thought and effort into understanding the subject which you critique?
Be humble and honest to learn.
Or....mock gender roles if it doesn't make sense. Like so:
Your sphere of influence is less limited than you think.
That is true. It might certainly reduce your pool in quantity, but it doesn't affect quality as quality is subjective to you. Thus, just like with attractiveness, there's someone to complement everyone. Someone who finds your brand of "masculinity", their
brand of maleness.
There's no guilt I want to raise in you. Just, hopefully, critical inquiry.
