in really basic, simple terms. BUT, if you really want to make your point, you might try being nice to her.
In fact - as distasteful as it sounds - you might go out of your way to do some nice little things to her.
People learn about tolerance most easily when they see it in action.
And if she starts chattering about Jeebus, either change the subject or tell her you do not want to hear about it, that to you, religion is a private and personal matter, and Jesus said to pray and worship in private. Tell her you take what Jesus said very seriously, and you're sure she does, too.
Wanna blow her mind? Do ya, huh?
Memorize this, and recite it to her:
Matthew 6:5-7
5. "And when you pray, do not be like the hypocrites, for they love to pray standing in the synagogues and on the street corners to be seen by men. I tell you the truth, they have received their reward in full.
6. But when you pray, go into your room, close the door and pray to your Father, who is unseen. Then your Father, who sees what is done in secret, will reward you.
7. And when you pray, do not keep on babbling like pagans, for they think they will be heard because of their many words."Man, this is the opportunity of a lifetime! True guerrilla theater!
PLEASE do it. PLEASE????!!!!!!!!!
