When you talk about "secular" are you meaning non-religious, or anti-religious ?
The normal use of secular would just be non-religious.
My feeling is that when the OP, who is most likely hyped up on Ron Luce's battle rhetoric, talks about secular music, he's referring to what Ron personally objects to. Look at the bands he's listed, these aren't just secular bands, these are bands that certain Christians have deemed satanic, but rarely ever are. How come musicians like Pink, U2, Aerosmith, Madonna, Snoop Dogg, Snow Patrol, etc. aren't listed?
Everything you listen to or hear has to be filtered through the written word of God and tested to see if it's glorifying to God. That includes Christian music today that is so popular. There is more that is damaging to a Christian in today's Christian music than you will ever find in anything by the band's listed above by the OP.
Personally I listen to heavy metal music and other secular music as well, while there are references to satan in a couple of the songs I listen to, it's not outright glorification of him. Alot of heavy metal music deals with themes other than the devil. It is probably the among the most intelligent and creative music out there.
Plus, another factoid the OP probably doesn't want you to know is that the "evil" heavy metal bands have Christians in them. Iron Maiden is one. The drummer Nicko McBrain became a born-again Christian in 2000. Their music has been influenced by his conversion to Christianity and is dealing with religion in a some of their more recent songs. What we as a Christian site have to stop doing is deciding for everyone else what is "Christian" and what is not based upon our own personal feelings. What happened to loving people where they're at? You don't want to listen to secular music, fine, don't. But don't make it into a pseudo-sin for others because it doesn't match up to your preconcieved notions of what is right according to you. Also, more bands than just the ones the OP has listed are discussed in that sub-forum, which is open to all people, not just Christians. That forum doesn't exist just for Black Sabbath, ICP and Ozzy and his music festival. This issue has already been dealt with, by CF. They put that sub-fourm in the area of this forum that is open to everyone. I think this guy is just trying to stir a pot that need not be stirred anymore.
