Most countries have annoyed their neighbours at one point in history, but with China, it has been going on for decades. It is a very oppressive, utilitarian country with very poor human rights record that are making our washing machines and things we buy each day, so it is very necessary to this topic to be honest guys, and no real need for someone to basically say "oh lets just talk about this, not that". They are all linked with each other.
I don't really see how one has to justify why they would buy a product purely based on where it is from and especially if it is from their home country. While I think that can be foolish, and I think I would buy something based on its performance, I can see why and admire why people do. It is no bad thing looking after your fellow countrymen. You buy a home-grown product, you have helped pay for a worker in your countries job, for them to have an income, for them to pay taxes so on and so on and crucially, keeps the money in the country.
This is not high level economics, it is very basic common sense.
But to be honest, China isn't a part of this topic, so probably doesn't make a difference anyway, but it is an interesting debate anyway, probably good for another thread.
