Starlightprincess - I do not mean to offend, but it comes across as if you have something to prove about being British yourself. You said that some of your parentage is not of this country and I am wondering if you deep down feel that you have to validate your belonging to this nation more than others. I say this as you have made statements such as:
"I can understand anyone who emigrates to have a longing for their homeland, but not people who are born and bred here, as this IS their homeland."
Massive sweeping generalization that I am sure my DP disagree's with. He was born and bred here but he feels that the English are not as accepting as you are putting across.
"I love my Jamaican heritage, and am proud of it. I am curious to know and learn about my family. But a longing to 'return to my homeland'? Not at all. I'm English, first and foremost as I was born and bred here. Jamaica is one half of my heritages ancestral home. I long to visit, but not because I miss it, how can I miss it? I'm not Jamaican!"
Also, you seem to lack knowledge or understanding of your Jamaican heritage. You realize that this same great nation that you are talking about kidnapped your ancestors from thier homeland and brutalised them before dumping them on an island where they recieved further brutalisation? Some English people think of you as a mongrel half breed, I hope you know that along with your fierce patriotism. And many, many of them would quite happily put you on a boat and ship you back to a homeland you seem very ready to deny. So yes, you have the freedoms you have mentioned, but many would dispute that you even have the right to call this your homeland due to your Jamaican heritage.
You are talking about this country bending over backwards to accomodate all these foriegners (to a certain extent I agree, even as a foriegner myself), but keep in context how other nations have bent over backwards to accomodate the English. This includes your ancestors, who would have been slaves to the Englishman, working the fields in herrendous conditions to provide England with profit made on the back of slavery. Maybe then it is time for England to give a little back to the other nations of this world.
