I respectfully disagree. I have no issue with polygamy or polyamory so long as it isn't abusive.
Since you're bisexual - what if a bisexual person wanted both a male and a female partner?
What if someone wanted both a transgender and a cisgender wife?
Or both a MTF wife and an FTM husband?
And then there's conjoined twins... what are they supposed to do for marriage?
And also you do realize that polygamy is practiced in the Bible?
MY EXPERIENCE WITH A TRANSGENDER COWORKER:; OUR NEW EMPLOYEE WANT TO BE CALLED "SHE"; I IDENTIFY AS A BISEXUAL POLYAMOROUS NON-BINARY TRANSWOMAN AND A CATGIRL; I was hoping that our new trans coworker would be a little bit closer to Emma Ellingsen; I'm quite disappointed that this is the first trans person I've ever really met personally
