It is not limited to religion..
Thanks for being honest that religion is flawed and marked with corruption. Now what are you going to do about when you argue for your religious beliefs? Will you be sure to have the highest integrity regarding evidence, objectivity, reason, and truth? If you say yes, and then are caught posting irrational and misleading claims, you will continue the corruption of religion in debate.
Furthermore the fact that dishonesty exists, does not mean that somebody who comes along with a "sweeping brush" to defame belief in God, is not being dishonest themselves.
Reason is a process that begins with skepticism. If theists are going to engage in debate then they need to follow the rules of logic and debate, not the rules of religion, which are deceptive and misleading. If anyone defames the many ideas of God it is theists who are not credible, who are deceptive, who make claims they can't or won't defend, and pretend their beliefs are true and have an authority that doesn't exist.
I don't care what a theist believes. You can put underwear on your head and dance naked under a full moon if you think that gets you closer to God, knock yourself out. But when you engage in debate about your beliefs, rituals, your history, your assumptions you begin at zero, and you need to show every part of your religion and belief is true, or likley true. You get no freebies. You have to earn respect for your ideas and beliefs in debate. If you don't respect the process, then you don't respect others.
