PS: Someone might quote in that regard the - as such beautiful - Benjamin Franklin sentiment They who can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety.
Which IMHO works well in a largely homogenous society, but in the reality of the 2017 status with tens of millions of illegal immigrants intent on destroying their host country should perhaps be reconsidered. Penicillin was invented for good reason...
All informative. Thank you.
