the double standard

we have this current meta that allows people in bronze to just pick whatever in the support spot. also play however they want too. this season as an adc main i keep getting stuff like who then takes all the kills when i go to make the killing blow. they say sorry. so i let the 1st one go. so instead of with there gold being enough to buy a . they instead buy get . then proceed to steal more kills. i have also gotten several teams that said "just make it work " when i get as my support. when i am in that same selection and say u know what i too will go off meta they go ballistic . i want to know why the ADC has to pick within the meta and support according to the team can build pure apc and ward like shit. then totally be on the side of the support. if my support dose not build a sightstone i play purely defensive. i get supports that say "dont worry ima get you fed. i am a great support". then i lolking there ward numbers and builds. 30 minute games with 8 wards placed. 30 minute games with 7 wards placed. yet the team still tells to just deal with it instead of trying to curb the guy in the support spot to actually pick a support and build like one. can anyone tell me why this double standard is rampant? that is all i want to know.
