Every time I get annoyed by some nonsense posted on Facebook by some fundy nutter, and seriously consider abandoning Christianity and becoming a humanist, the member of this forum who started the other thread that this is a reply to comes out with some outrageous, one-sided slur against Christianity, and reminds me how bitter and negative I found myself becoming during my year out back in 1992-3, before I came back to a much more liberal version of the faith, which makes me decide not to throw it over just yet - so keep up the good work for the gospel, RJG! 
There are a number of Secular Humanists that hold religious beliefs, I think most religion based organisations mainly try try to represent the Secular Humanist section of society as their sworn enemies mainly because we keep on hitting at the many privileges the various religions have and in a lot of these cases it involves the financial advantages that accompany these privileges.
Secular Humanism's main aims are for a level playing field like at the moment we're trying to rid the The Bishops Bench from the House where 26 of these Bishops sit there in the H o L as of right whilst having no objection to Bishops being there on merit.
Then the Chaplaincy in the services, prisons and the N H S, whilst as far as I know there's no objection to the chaplaincy services in these places whilst they do some very good well intended helpful works for people in these places it also happens to be a nice, not so little, earner for mainly the C of , E in the UK where these services, are 100% government funded.
Any of the Secular Humanists I know have no wish to curtail any of the chaplaincy services they generally do a good job I don't think the whether of if they do a good job or not is a up for discussion in any way, it's the the source of where the funding comes from, surprisingly, doesn't come out of any of the religion based organisation's coffers.
The unwanted Catholic academy in Peterborough just over 80% of the local population don't want a religious educational type anything in their area the point being when opening these places the religions only need to supply 20% of the funding to open it up for use and then our government funds the rest from then on, why should we, UK citizens be funding the promotion of Catholicism in this academy or anywhere else for that; just another case of religious privilege that the secularist humanist organisations are trying to gain a level playing field, no small wonder the religious organisations do their best to demonise Secular Humanism.
On the other hand the secular society has been collecting donations for the relief of the predicament the Rohingya are in, in Myanmar, it's Secular Humanist approach of where it should be a case of freedom of religion for all people and freedom from religion as well, that's roughly my understanding of Secular Humanism.
