Is it acceptable to shove hard a person who walks into you in public?

i shoved this dude and his girl hard since they were walking and looking at their phone in a narrow path, and i tried to avoid them both, but they continued walking into me. i don't ever get taken for a dickhead, so i shoved them. they then give me weird looks around campus, but i don't give a shit. respect others' space, and that's fine. they've been doing it for weeks now, but i don't care, i just go around my day.
