Asante Samuel says he doesn't blame Marcus Peters one bit for going off on a heckler Sunday ... 'cause he used to go hard at trash-talking fans too -- by callin' out their moms!!!
Peters has drawn serious criticism for exploding on a guy during the Rams-Eagles game ... but Asante tells TMZ Sports that kind of fan-player interaction has been going on for years.
In fact ... the ex-Eagles corner says he used to go after dudes in the same fashion -- talking trash about everything from fans' kids to even their moms!
