If you can't disagree with somebody without insulting him, you are either a troll or a resident of a certain area in California where they default to insult as normal conversation.
And if you can't taste the metallic taste in some canned food... well that's normal. Some people can taste it, some can't. It probably has something to do with what scientists say about some people have different taste buds than others. They claim if tastes were colors, some people would taste in bright primary colors while others would taste in pastels.
To me, and to many others, some canned foods taste metallic. If you can't taste it, be happy.
