What is really important is that you don't confuse support with a healer in WoW.
A support helps but that help has many different forms.
As many are pointing out, one of these forms is auto attacking the enemy (and using abilities to do the same). Many supports forget that.
Supports are not heal/aura bots. Sure some can heal but that's not the main focus (despite maybe when playing Soraka and even she should auto attack).
Now in case you don't understand some phrases in the post you are quoting, I'll try to explain. If you understand everything, just stop reading here.
Harass: putting pressure on the enemy by attacking him.
Poke: spikes of incoming ranged damage.
bot lane: bottom lane, this is one of the three lanes (top, mid and bot)
ADC: AD carry. A champion that focuses on getting AD (attack damage) items and deals much damage with his auto attacks. Commonly lanes with a support in the bottom lane
lane phase: At the start players are in different lanes. At your level propably 2 in the top lane, one in the middle lane, and you and on other in the bottom lane. There you try to bring the enemy towers down. At some point in the game you will group with your team and go for game objectives in a group. Then the laning phase is over.
snow balling: if a player gets "fed" (many kills), he gets stronger than his opponent and therefore gets more kills. Kinda like a snowball becomes bigger when you roll it through more snow.
carry: as in AD carry, explained above
I really hope I didn't make any grave mistakes with that or made it more complicated.
