Do people really think of the support role like this?

Just finished a game as Thresh with Jinx ADC, Heimer Top, Ziggs Mid, and Gragas Jungle. Enemy team consisted of Riven Top, Lee Sin Jungle, Katarina Mid, Mordekaiser + Blitzcrank Bot. Keep in mind, this is a game in Platinum Elo where people should be somewhat more knowledgeable about the game...

Start of game, enemy team invades through red buff blue side (could easily see it coming). Jinx gets pulled and dies, everyone else made it out somewhat ok. Laning comes along, I try to consistently harass Morde to keep his passive down, and jinx spams rockets to shove the wave. I say to not push against Blitz, so we try to freeze where the wave was. My harass starts to get Morde low and jinx gets closer to go in, Lee Sin came bot just as jinx was going in and gets a kill on her, with the kill being initiated again by a Blitz hook. Later in lane, we get a double kill and things look better. Back and return to lane, moment Morde hits 6 (and me and jinx were just reaching 5, that W passive though lol) Blitz goes in with W and goes to pull Jinx. From when Blitz started W, I space away from jinx so I can prepare to throw a lantern if needed. I figured the distance between Blitz and Jinx was big enough where she could dodge with either flash or just a side step, but it still hit and she ends up dying. Now with the way lane was going, a bit of anger was expected, but what jinx specifically said surprised me.

"THRESH WHY HAVEN'T YOU BEEN TAKING THE PULLS FOR ME" "IF YOUR A GOOD SUPPORT THEN TAKE THE PULLS AND DIE FOR ME" (that's not my bad grammar, just putting back in what I remember her saying) ...really? Do people really see support as fodder to die for the ADC and take all CC skillshots that they could dodge, but apparently don't? I asked jinx if I was somehow supposed to know she wouldn't be able to dodge the pull and die for her, she got mad and began to afk in base since I didn't understand that... I asked in all chat what everyone thought about this piece of blame...and I was again surprised. Most of the other people aside from Ziggs and Blitzcrank sided with Jinx. Just...what? Why do so many people see one of the roles in League of Legends as something so demeaning? Please, we need to make the community realize that support has its own importance aside from fodder.

As a start, supports aren't even meant to be dedicated to the ADC, the support is dedicated to the team, to keep allies alive with shields and peeling, or to apply multiple amounts of CC on the enemy team to allow your allies to deal massive amounts of free damage. Supports are meant to be kit and item active reliant. It's why most support items are low gold cost and why supports work well in duo lanes without much gold. The reason why they are by the side of the ADC during laning phase is because ADCs also work well in a duo lane environment, where they don't need much experience but more of high stat items (more gold, less experience).
