Sorry, but this is exactly the kind of dangerous misinformation which needs to be cleared up so we can have sensible debate on GM.
he gene may become more like an infection, reproducing in other animals and spreading like wildfire.
No it can't. If you spend long enough in a room with someone with green eyes, will you "catch" green eyes from them? Of course not. Genes are passed from parent to child and do not simply cross from organism to organism. (Actually, this is not strictly true. Some bacteria do exchange genes, but this only occurs in very specific cases and wouldn't happen in a mammal.)
Or, as mentioned, the animal could mutate and get different traits.
So can any animal, genetically modified or not. This is quite fundamental to the theory of evolution.
Just because it may be killed off easier does not mean that it will not spread.
No, but it will only spread in the short term. The damage would be far more limited than if the gene was beneficial to the organism.
Read more about foot and mouth disease if you don't believe me...
I don't think I need to, I'm already surrounded by it, and I've heard of nothing else for weeks. Perhaps you need to read some more about it!! Then you would know that it has nothing to do with genetic modification. F&M is an extremely contagious airborn virus. Just because it weakens the animal it infects does not mean it won't spread, because F&M (like any virus) has effectively completed it's "life cycle" and already been passed on before the animal even becomes ill.
F&M is something totally different to GM and shouldn't be compared...
Sorry if this seems a slightly harsh message. I do agree with you in some respects. Whilst I don't see anything inherently wrong with GM, it has almost unparalleled potential to damage our finely balanced world, and therefore needs to be treated with incredible caution. We are already polluting the world in many ways, but GM could be far worse because unlike greenhouse emissions, CFCs, radioactive substances etc, the pollution of a species genetic makup is irreversable.
But, if we are going to argue this viewpoint effectively it's important to have our facts straight.
