Exactly ... why should bikers specifically behave in
any different way to hikers in terms of protecting trails and the trail
experience ?* Do bikers not turn out, in general rather more than hikers,
to maintain trails ?* The answer to these questions, of course, is that
they don't and they do.

This business about bikers maintaining trails is the biggest
laugh ever to come down the pike. What bikers do is use that as an excuse so
they can build their own outlaw trails designed for only one thing - biking.

At least they're doing something to protect and maintain the experience for others. You're doing nothing and castigating others, who are prepared to put something in, for unsurprisingly favouring their own activity when doing that work.

It is wrong to do it on trails used by hikers because
there is
a conflict of purpose among other conflicts. Only
hooligans have no regard for
others.

Then that, clearly, makes you a hooligan by your own
definition.* You've stated, again and again, that you don't care one jot
for mountainbikers and rejoice when they are killed and injured.

Well Hells Bells, I am not killing them.

I didn't accuse you of doing so. You said "only hooligans have no regard for others" and then clearly demonstrated that you, yourself, have no regard for a whole section of the trail using population. You are therefore, by your own definition, a hooligan.

Hoist on your own petard.

Your purpose argument was shot down long ago.*
You want to ban trail runners simply because they are there for a different
purpose.* Your fundamental premise has no logic.

The logic could not be more clear and direct. You are only
entitled to be on trails only if you there for the purpose of appreciating
nature.

Says who ? You ???? !!! I think you will find, if you can be bothered to read, that public spaces are constituted for the public and wildlife.

So, your restriction on purpose is something you've come up with, to suit your own ends, and which is entirely valueless.

The park managers, who you continually castigate, are doing precisely what they are supposed to do; balancing public demand for access and recreation and the protection of the environment and wildlife. There is zero reason why they would ever apply your purpose test ... it's not an objective and nor should it be.
