We shouldn't hate the monarchy, necessarily. We should hate monarchy as a concept.

It's archaic, it formalises and legitimises unbelievable levels of inequality and elitism, and it gives rise to at least the strong possibility (and in the UK's case at least, the actuality) of a tiered legal system, with some laws simply not applying to some people because of their position.

It's a repulsive idea, based on historical might and hereditary right, and with no regard for democracy or equality of all people.

They have influence, not governing power

The old man that this post is about literally does have governing power, not only in the UK but also in 14 other countries including Australia and Canada. A common argument made by monarchists is that the monarch's actual influence is negligible, and their governing power should be ignored because it is only ceremonial.

As Wikipedia puts it:

Royal assent is the method by which a monarch formally approves an act of the legislature, either directly or through an official acting on the monarch's behalf. Under a modern constitutional monarchy, royal assent is considered little more than a formality. Even in nations such as the United Kingdom, Norway, the Netherlands, Liechtenstein and Monaco which still, in theory, permit their monarch to withhold assent to laws, the monarch almost never does so, except in a dire political emergency or on advice of government.

But... there is a catch:

It turns out that there is also a less formal process (or a "parliamentary convention"; another part of the UK's heritage is having an "unwritten constitution", whatever that means) called King's Consent whereby the monarch, in secret, is consulted before parliament is allowed to debate anything which might affect their personal interests. And it turns out, a lot of things might affect their personal interests, so, this procedure has been and continues to be used to review, shape, and in some cases veto, numerous laws before they are allowed to be debated by parliament.
