The melting pot you credit as an asset to our country is exactly what Trump and his followers seem to want to greatly restrict.
So wrong as to not be in the same universe. Immigration does not equal illegal immigration, not the same.
Show one single direct quote from Trump (or any of the folks here who people seem to think support him) that is blanket against legal immigration, I quadruple dog dare you.
All sovereign nations control immigration to one extent or another - to include legally picking who can and cannot immigrate - without a border a nation is not sovereign. This can include religious, ethnic or political grounds, and has, not only for America but for many other nations (like Mexico, or Cuba or Japan - basically all of them). Many do so with fences and walls (e.g., Vatican City).
Many if not most of us are immigrants - my mom's family has been here since the 1700's but my Dad's family didn't come over until the early 1900's. Came in accordance with the laws in place at the time - processed in through Ellis Island direct from Poland.
Trump is married to an immigrant (Slovenia), his previous wife was an immigrant (Czech) - look past the 2 second soundbites and do some actual research and think for yourself.
