Although discrimination of any sort is uncalled for and unchristian, nonetheless, no Christian should be involved in these demonstrations. Among the list of living for the flesh is "revellings" (Galatians 5:21) in which issues get people worked up and feel that they need to parade and rally for their cause. That is not a Christian activity. All these unfair acts are going to happen and have been happening. Attitudes are not going to change unless people are converted. And that is the only commanded method we are to use. "Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, [even] unto the end of the world. Amen" (Matthew 28:19-20). The world will always be dealing with these distractions. We have a mission to go and "hasting unto the coming of the day of God" (2 Peter 3:12) for "this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come" (Matthew 24:14), which is not just any gospel but is "having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people" (Revelation 14:6).
