On illegal immigrants

1 minute read

If a person enters my house without my permission, I suppose I have the right to ask the person to leave, and if they refuse, I may force them to do so. By analogy, if a person crosses the border into a country without permission from the government of that country, I suppose the government has the right to ask the person to leave, and if they refuse, they may force them to do so. Therefore, I see no problem that some government cracks down illegal immigration and attempts to deport illegal immigrants (although there may be exceptions on an individual basis, for example children that were taken to the country by their illegal immigrant parents and grew up for quite some time, losing tie to their country of birth). It is just common sense that follows from the fundamental principle of a liberal society that honors property rights. A corollary of this argument is that I do not understand why some people (typically the radical left or whatever they are called) organize protests against the crack down of illegal immigration.

Among amateur tennis players, including high school and college players, I think it is fair to say that UTR (Universal Tennis Rating) is the number that we look at to measure the skill level. UTR rates tennis players by a number between 1 and 16 something, with a higher number indicating higher skill level. According to the Wikipedia page, UTR was developed by a private company in 2008 to evaluate junior players.
