I don't see why it is fine for you to run a softfork that activates after 75% of the hashpower is using it or a hard fork that goes life after similar thresholds. Double standards? It would still show that the majority supports something.
All soft forks so far have only been enforced after a 95% threshold (and this will apply with SegWit as well).
The only people trying to push for a 75% hard-fork are Bitcoin Classic, Bitcoin Unlimited and Bitcoin XT (the latter being now defunct).
