Polish Clarinet,
Regarding political involvement, in particular Voting, if the WT in 1999 said it was a conscience matter - they appear to have changed their minds again since. Here is the quote from "God's Love" p214:
Voting in political elections.
True Christians respect the right of others to vote. They do not campaign against elections, and they cooperate with elected authorities. However, they remain resolutely neutral with regard to the political affairs of the nations. (Matthew 22:21; 1 Peter 3:16) What should a Christian do in lands where voting is compulsory or in a situation where feelings run high against those who do not go to the voting booth? Remembering that Shadrach, Meshach, and Abednego went as far as the plain of Dura, a Christian, under similar circumstances, may decide to go to the booth if his conscience permits. However, he will take care not to violate his neutrality."
