The practice of not shaming or harassing over fictional ships.
No matter how taboo or even problematic the
ship may be a person who is pro
ship, or a proshipper, doesn't care and simply doesn't engage.
The term pro
ship was created on tumblr (at the
time called anti-anti) to respond to "anti
ship" people who would tag a
ship with the word anti before it and send hate in the tag.
Although some people, who still believe fiction doesn't affect reality on a 1:1 scale, have distanced themselves from the "community" have taken new labels such as pro fiction or faia, etcc. they still stand for the same things.
What pro
ship stands for is to accept and not harass people who
ship something different, even if it makes you uncomfortable but even more to stand against hate and harassment.
Some people may not stand for that though, and they could be pro
ship and still harass people. Those people are not really part of the community because they are part of the harassment problem.
Lastly, pro ship doesn't stand for problematic-shipping, many pro shippers don't appreciate problematic or dark content.
Example 1
Person A: Although I am proship I do not like to see (2 characters from a dark
ship) as the age gap is too much for me.
Person B: that's ok! I'll make sure to tag this
ship so that you will be able to mute the word and not see it around
Example 2
Person A: you shouldn't condone this stuff because it's
disgusting and wrong
Person B: I want you to know that i do not condone in any way this kind of behaviour outside of fiction, please block me if you don't like this works or pro ship people like me
