MarvelComics!Sigyn is no tradwife. That's a Goddess with TWO jobs (She canonically had missions for Odin AND was a handmaid to Frigga). Her only sin was to love Loki too much and foolishly think she could make him love her. You'd think Loki fans would get it ^^' (also, hasn't she suffered enough? She lost Loki's love, her sons, her tongue, her life, her dignity, no one even mourned her... Anyone with a heart would feel sad for her. Enough!)
Shipping a Norse god with his wife (a wife he has been married to since the Germanic pantheon, mind you, and who supported him when EVERYONE ELSE abandoned him) is not "promoting conservatism".
Sigyn is not a self-insert. She's a very old Norse goddess. HOW COULD SHE BE A SELF-INSERT? Besides, I'm sorry, but who would want to insert themselves into her fate/isekai as her? Yeah, sure, Loki would be your hubby, cool, BUT WE ALL KNOW HOW IT ENDS. NO ONE wants to see their own kids dead, or your beloved bond with the guts of one of your sons. NO ONE. Plus, I'm scared of snakes. So it's a big nono for me XD (and I'm aroace, so... I just love their love. That's all)
Making super aggressive posts on that bloody confession blog is useless and unhealthy. Some of the ones I saw recently sounded pretty parodic too. I wouldn't be suprised if it was just haters making fake Logyn/Sigyn confessions and exagerating stuff ON PURPOSE to create ship wars and drama. Advice of the day: BLOCK THAT BLOG.
