All opinions for and against something are equally valid

All things are possible

Now with the inconsistency of language
all possible views and their negation are
now possible and equally valid Thus the
philosophies of Kant Hegal Plato
Aristotle etc all philosophies and the
negation/opposite of the philosophies of
Kant Hegal Plato Aristotle etc all
philosophies are now possible and equally
valid

and

in the every day world this means that all
views are valid but so are the opposing
views valid Thus all civil rights views are
valid ie pro gay marriage is valid but so is
the opposing view ie anti-gay marriage is
valid
as Each view contains within it its negation
as all views end in meaninglessness

Thus
We can now just treat all views/ philosophies esthetically that is for their logical and argumentative beauty rather than for any scientific or truth value just like one treats poetry painting music for their esthetic beauty

Some things are objectively true (in some context).

Some things depend on your values and priorities, and these can differ between people, and at different time in history. For these, the best you can work on is opinions and preferences.

Some things are too complex to have an objective truth with our current state of knowledge. Again, opinions are all we can depend on.

In a democracy, the most common opinion carries some weight with the policy-makers (eg politicians and civil servants).
- In an informed democracy, the known facts will influence the opinions of the public and the policy-makers.
- In a learning democracy, opinions will be tested in a trial before they are deployed nationwide.

Unfortunately, most policy-makers believe that they must know it all, which prevents them from learning anything useful before the next election.

All opinions for and against something are equally valid

So if I'm of the opinion that this statement is nonsense, then that opinion is equally valid to your opinion that it is true. That means you can't really say that all opinions are equally valid with any certainty, because that opinion in itself is disputable.

Most people hold the opinion that eating usually stops hunger.
Presumably, when you get hungry, rather than eating you try oher things to make the hunger go away.

Let me know how that works out for you.

Similarly, most people hold the opinion that pissing on the carpet is a bad thing.
Remind me not to wear sandals if I visit you.
