Of course they should. Those under 30 are generally going to enjoy the benefits and endure the drawbacks of any political decisions made for decades to come.

A better question is, should people over retirement age (or a higher threshold) be asked about politics, given that their life expectancy means they will have less benefit to enjoy and less drawback to endure? Let's not forget that people tend to become increasingly set in their ways as they age, which also limits the ability to properly respond to changes; just look at the internet.

The above is not a serious assertion, mind you, just a counterpoint.

Some may argue experience, but experience is relative. For example, a mind with greater intelligence will gain more from the same experience than one with lesser intelligence. A more malleable mind will gain more from the same experience than a less malleable mind, favoring the young. A mind with more foundational knowledge on a subject will gain more from the same experience than one with less foundational knowledge, generally favoring the older and more educated. I believe that people of all ages are potentially valuable- even some of those too young to vote yet. I would favor age being removed as a requirement for voting, but rather the ability to demonstrate knowledge of how the system works (as well as knowledge of the general platforms of the politicians in question) via some kind of test given when registering to vote/renewing ones registration. Though obviously how that test is composed would be very vital, and certainly prone to corruption. If a 12 year old can demonstrate that he understands the system and his candidates platform, I say let him vote. If a 42 year old can't, I say show him the door.

The youth contingent of every nation can handle politics in good stead so why shouldn't they be taught of politics?otherwise it would be absurd.Politics turn into party politics the moment it falls into the established noveau riche and old blokes.Youth must have some opinion towards politics

people under 30 don't know much about politics?

Even if that's true (which it is in some cases, not all. I for example, am under 30, and am very politically aware, and I have many friends who are and many who are not) how does this argue that people under 30 shouldn't learn about politics? Even if everyone under 30 didn't know much about politics, that's not a reason why they shouldn't learn about politics.

DEFINITELY! I am not saying there aren't ANY, but there are not enough young people who understand and take part in political activity. That is why I organised a mock election in my school, and taught my classmates about the political process. I was on the national radio because of it! And guess why? Because it is so rare for a young person to like politics. If you are wondering which party I am (which you shouldn't be if you read my username), I am a Conservative. :)
