'Feminist Father' t-shirt shared more than 200,000 times on Tumblr

CHERRY HILL, N.J., June 20 (UPI) -- "Rules for dating my daughter: 1. I don't make the rules; 2. You don't make the rules; 3. She makes the rules. 4. Her body, her rules."

That's the message on the back of the "Feminist Father" shirt that Tumblr user Kristine Speare gave her dad for Father's Day. After she posted the image on the site, it began to go viral and the picture has now been shared more than 200,000 times.

"Yeah, that's my dad!" Speare wrote. "I got him that shirt for father's day and now his back is kinda famous."

The shirt has become so popular that it is now available on Zazzle for $48.90.

The 20-year-old describes herself as a feminist, coffee addict and book lover in her Twitter bio.

"He's very supportive of me and the decisions I make for myself; he cares so much about me and my passion for feminism," Speare told Yahoo Shine through a Twitter message. "He completely agrees with the shirt's message."
