Except those of us living in Poland know that CBOS tends to get polls wrong due to the polling methods used.
Well, if that so that renders your 'friend's' Harry line of argument null and void.
The number of people who actually do go to church is very different, becausewhat people say and what people do all often rather different.
If you say so. It could be read both ways not only the way you take it, i.e. more people actually go to church than CBOS states.
Of course, not everybody who is in church on a particular Sunday goes to church every single Sunday.
Again, that line of argument can be used to debunk your claim. Not everybody who isn't in church on that particular Sunday doesn't attend Church services in some or most of Sundays in a year.
If we assume
You can assume whatever fits your fancy it doesn't mean that your assumption is correct and reflect reality.
from 57% in 1982 to under 40% last year
So from 1982 to 2015 attendance fell from 57% to 40%. If we take into account that some of those people attending church in 1982 died, if we adjust for the decline of population due to emigration, for a greater number of people working Sundays (only few worked Sundays in 1982), then we can assume that 17% of difference is not that great. Yes, some of those people don't go to church due to fashion, laziness, 'liberal' lefties ideas but only some and the latter is not a number that can be determined.
What we know is 40% is a number that shows up in some or other of the USA research of the subject and that number is lowered by one or other argument to about 20% of those who actually go to Church as opposite to those that say they go. Goes as it may we know where Harry got his 20% number from.
However here we have a number of those who actually show up. So you failed again as usual.
to under 40% last year. one should note that the figure of 39%
Nah, 40% is in fact 39% and 39% is not real that but only 30% as the great Harry Houdini says. Why would we take his word for it? No reason at all.
they exclude from that number
whomever they exclude from that number they have been excluding them for years so if your argument had any consistency you would have to lower that number for 1982 by the same factor - instead of 57% should be 47%.
Instead of exploring murky ways of 'arry and his wishful thinking and questionable integrity let talk about something else. For example about that weird thread's topic and his even weirder OP. Like WTF?
