Toxicity to Losing against non-meta lanes

(Sorry if this isn't the right place for this.) So, I just had a relatively gnarly game. I was Karma support with a Caitlyn ADC. We were unfortunately against a Lissandra and Camille bot. Camille with the support item, Lissandra APC. It seems that just because they weren't in their standard roles (Top and Mid), that miraculously they would be bad. This was in fact, not the case as there would be a quick engage from the Camille, follow up burst from Lissandra, and the occasional gank from the enemy jungler.

My ADC was ahead in farm, we didn't die particularly in lane, we died out-of-lane during team fights. Our toplaner was particularly toxic saying we were intentionally feeding, with a few remarks from the midlane "imagine losing to camille support" even though she wasn't building support (Besides the one item). We didn't even lose first tower, we lost our tower well after turret plating when the enemy jgler ganked and they could get our tower in one good push.

Please don't forget that just because they aren't in their standard roles, does not immediately make them bad. Please try to assist your team against odd picks all the same.

(Quick edit to explain that I don't want anyone reported or flamed, this is just general player behavior that I've unfortunately noticed in a few games and as I said, if it doesn't belong here, I'll remove it-)
