Sheith also got more popular around here after S6 and S7 happened, because it became easier for Keith players to point out that they don't want to ship with Lance (and many of the ship-pushing Lances got tired of the show for not catering to them).

IDK where this anon got the idea that many Shiro players don't ship Sheith ... there's one, maybe two that I've seen. It's a popular ship on both sides of the equation
