Concerning your post #(131) in the first 'Christians in Politics' thread, yes, plumbing is not politics. So? It is a vocation just like politics is a vocation.
You first indicated a believer should only engage in the politics of the Church. Then i asked if a Christian plumber should only plumb Christian homes? To which you answered there was a difference citing pornography and other wrongs done by politicians. But that analogy doesn't work.
Just because one is a politician doesn't mean he has to do evil things. A plumber can do the same evil things. Just because he is a plumber doesn't mean he does them. Your analogy doesn't work.
In other words you have no credible reason to give as to why a Christian should not be in politics.You just don't think they should.

Yes, there are vocations (like prostitution, the porn industry, cult leaders, etc.) that are un-Christian.
But your insistance that saying one vocation is wrong is to say all vocations are wrong is a faulty logic.
Saying Christians should not be involved vocationally in the porn industry does not mean Christians should not be involved in another vocation (like plumbing).
The reason I believe Christians should not be involved in secular politics has nothing to do with vocation. It has to do with the nature of vocations applied to a specific context.
There is nothing wrong with a Christian bring a photographer. There is a lot wrong with a Christian photographer becoming involved with the porn industry.
There is nothing wrong with a Christian being involved in the affairs of the Church, the ministry of the gospel, holding a leadership position in the congregation, etc. There is a lot wrong by assuming those roles in the affairs of the World.
Thus is not mere opinion. It was the position of the church for centuries. Antiquity does not prove the position correct, but it does prove it a biblically based position and a legitimate interpretation.
Paul tells us not to judge those outside the church. You say there is nothing wrong with judging those outside the church.
Christ said the World is opposed to God, is already condemned, is fading, and is something we are called out from. You say it is fine to engage in the affairs of the world.
Peter said we are to be separated from the world, to exist as a holy people. You say we are to engage the world by becoming a part of the world system.
Jesus said that those who become caught up in the affairs of the world will perish. You say we are called to be a part of worldly affairs.
The credible reasons are there, you just cannot see them. Your position is not only mere opinion, it is justification for active rebellion against God - not because I am right and you are wrong but because you fail to even engage those passages.
You just put the blind eye to the scope and complain you cannot see.
