But, Paul says that we are only to judge those within the church, not out of it. He says that we must go out into the world, it can’t be helped. I would say that using Windows is a neccessary part of ‘going out into world’ in our society.
Read what Paul has to say in I Corinthians 5.9:
"I wrote to you in my letter not to associate with sexually immoral persons–not at all meaning the immoral of this world, or the greedy and robber, or idolaters, since you would then need to go out of the world. But, now I am writing to you not to associate with anyone who bears the name of brother or sister who is sexually immoral or greedy, or is an idolater, reviler, drunkard, or robber. Do not even eat with such a one. For what have I to do with judging those outside? Is it not those who are inside that you are to judge? God will judge those outside. 'Drive out the wicked person from among you’
I think this passage means that we are only to judge those within the church for sin. Bill Gates is not Catholic, although his wife is. I think Paul is also saying that it is neccessary for us to associate with unrepentant sinners in order to live in this world, it can’t be helped.
Now, John Kerry, who claims to be Catholic, is wide open for critisim from us, I would say.
