Under Obama the AHCA provided insurance to those who didn't have it. Under TRUMPCARE insurance is being taken away. Great, right?

No there was no insurance under Obamacare.  Because insurance is where we pay against some supposed future outcome (rather like gambling!).  Instead of paying their health care bills are assigned for payment to other people who are being charged more for the same services.  This creating a two-tiered society and a system ripe for exploitation and corruption.
