There's are plenty of posts specifically dedicated to helping first time raiders. There are clans recruiting right now in #recruitment (crazy huh?) that specialize in helping newer guardians. I came back to destiny after HoW dropped and had no problem finding a group to show me both raids and PoE for my first time. And that was the "max Gally" era. Put in a little effort to find a group and you will find one. I realize you were complaining about "2 weeks after the raid" but at this point you could have done it.
