Article 18: most muslims disagree,many islam countries would kill you for conversion
Article 19: this one is silly, every government would persecute you for holding certain opinions even without expressing those opinions. Look at how alleged communists in the US were treated around the time this document was drafted. Or consider holding an ISIS or islamic terrorism symphatizing opinion,people have been detained and persecuted for far less. What if you are spreading the terrorist propaganda? No one will see that as your right.
Article 20) so all militaty draft violate human rights?
Article 21) citizens of any country that does not accept democracy are having their human rights violated?
The whole thing is silly. First of, most of the existing UN members did not sign. Of the members at the time, the vote to adopt this was not unanimous and therefore this document is not accepted by the sovreign governments of many nations at the time. You can say the UNDHR is the opinion of what some humans think a human right is,however it is far from a document all sovreign nations accepted as a defi ition of what rights humans have simply for being human. China and muslim countries combined alone would make up a population majority!
The UN is not an authority nations are subject to. UNDHR is not a treaty adopted by nations. It simply defines these trems as the western majority if the time saw it fit.
Now,there are rights almost all humans accept as rights such as the right to exist and the right to a fair trial (as applied by their society). These are obvious rights commonly accepted by most religions and an peoples.
Or if that isn't a good argument then consider that even the US (the sit of the UN) has been and is currently violating many of the UNDHR articles systemically, a US person should probably not talk about enforcing UNHDR against other countries. Everyone tolerating terrorists having propaganda zoom calls would be the only way I can accept UNHDR application of freedom to express opinion on other nations as a human rights.
My view: the UN is a diplomatic organization not an authority over nations. A document that can define universal human rights must be a treaty reviewed and accepted by legislative bodies of each signatory nation and it can be a universal right only if a super majority of nations and humans (counted by national populations) accept it as such. Look at the criticism section in wikipedia.
