Religion as a whole isn't the cause of religious terrorism, violence, discrimination, etc; religion is just a scapegoat that assholes use to justify their actions
Of course there are shitty things about religion. There are shitty things about atheism too. There are shitty things about all religions and ideologies. There's no such thing as "the perfect ideology," and even if there was then we'd still find a way to make it shitty
All humans are capable of doing bad things, whether its due to scientifically explainable reasons, an religious force such as Satan, etc. To just say "religion bad because it make people do bad thing" is incredibly ironic, because you're essentially doing what these hypothetical bad religions are doing: using your ideology as a justification to hate people who think differently from you
If you genuinely, wholeheartedly, unironically believe that religion is just a sham and a negative influence on everything it touches, then I encourage you to expand your worldview. Talk to people who don't frequent Reddit. Partake in religious media. Learn more about religious cultures. Hell, even just listening to religious Youtubers has given me a slightly better understanding on different ideas and philosophies about religion. There are such a thing as religious echo chambers, sure, but anti-religion atheist fuckheads also seem to forget that there is such a thing as atheist echo chamber
Anyways TLDR; you can't sum up an entire set of beliefs as moronic and useless just because you don't agree with them, because then you're just as bad as the people you're criticising
