Hate speech is not permitted, but any worship is. Should hate worship or worship of a god of hate be permitted?
Of course. Who is it that grounds our "unalienable rights?" God.
God has given us freedom (not held by some Christians) and responsibility. We are to train our minds and those of our children to understand the external world properly, and engage it in a manner reflective of Jesus' own engagement.
We are not to use our freedom to eliminate the free will of those who hold different views.
We are to win people over by our actions, arguments, and respect that they are also created in God's image even if they deny that fact and mock and berate us while doing it.
Speech codes are a product of atheist presuppositions. On this view governments are created so the intellectual elite can control the mob. Not to serve the people.
Donna Shalala has produced a speech code of Orwellian dimensions at the University of Wisconsin back in the late 1980s. It was ultimately deemed unconstitutional, but was an attempt to outlaw any speech people deemed offensive.
Now imagine what would happen if Obama could throw any reporter he wanted into jail because he was offended by what they wrote.
To be fair, the speech codes weren't that draconian.
But practice of religion... should be free.
Discussions about which religious views best describe the world we live in...should be free.
God has given us freedom.
We are the first culture in 6000 years to have the freedoms we have. We are only ~250 years in the making. It is too early to give up on freedom, especially religious freedom.
We do need to boldly and intelligently defend our Christian worldview in the public square. At work, with friends (who are interested), family, on campus, in classrooms, etc. We cannot forget the way Jesus and the apostles engaged people where they were at intellectually and proved their points with evidence and argument (not asking people to just "choose" to believe, as some ignorantly report). We should engage those preaching hate in such a dynamic way as to make it clear to all that they are "10 times a son of hell as..." just kidding!
Maybe we shouldn't follow everything Jesus did given our limits in knowing the heart of the person sitting across from us.
