What do you think about Vladimir Putin, the president of Russia, many accuse him of being a dictator because he has ruled since 2000?

What do you think about Vladimir Putin, the president of Russia, many accuse him of being a dictator because he has ruled since 2000, but Angela Merkel rules Germany almost as much the same since 2005 not get my wrong as Pole I'm the last person who would prise Putin but for Poland, we have a term limit for president max two terms because we based our constitution on American on and the first constitution of Poland was the first modern constitution in Europe and just 2nd after the American one 

and in ancient Rome was only a 6-month term limit for every Consule.

I'm just wondering why we accuse Putin of being dictator and not look at ourselves, for example, Mr Kaczyński who is the Law and Justice head of the party he is in our Sejm (parliament) since overthrowing of communism.

And I read that in the British House of Commons or/and in US Congress are MPs/Congresspersons who seat there for several decades I wonder does it not should be some kind of term limit for people sitting on parliament as it is for a head of state?
