Public corporate prayer and Mt.6:5

[stigg]

My nephew, an avowed atheist posted a pic. of several people (Tea party) on their knees in public prayer and claims that they are in violation of Mat 6:5
"And when you pray, you must not be like the hypocrites. For they love to stand and pray in the synagogues and at the street corners, that they may be seen by others. Truly, I say to you, they have received their reward." In a very wooden manner (out of context) this could appear to be a "great" argument to declare the people in the pic to be hypocrites in direct disobedience to Christ.
I understand Mt 6:5 to be a criticism of the self righteous Pharisees who loved to be honored by men in public.
Where in the new testament are we as christians allowed to corporately pray in public?
(I tried to upload the picture in question but it failed)

The point is not to flaunt the act to get praise. If thats your motive you are in clear contradiction of what christ said, otherwise no.
