Pray to be only directly to God (as opposed to any saints),
Roman Catholics don't pray to saints any more than we do (and we don't, it's a misconception of Protestants who don't understand the practice. They, like we, do not believe that the saints are dead but alive in God and do, obviously, believe that they are righteous and that their prayes avail much as the Bible says. 'Praying to' the saints is nothing more than shorthand for 'Asking the saints to pray for us'.
communion not the literal body and blood (only done in memory)
And yet every Church Father who wrote on the subject believed that Christ was truly present in the Eucharist and the Greek word anamnesis means much, much more than a memorial. Nobody doubted the Real Presence prior to the Refiormation, so how do you explain the attitudes of the first millennium and half of Christians if your view is right?
no purgutory (everything paid on the cross)
Here I agree, but Purgatory is a late development of RC belief (rather like the Protestant belief in a merely symbolic Eucharist is late development).
most extensive hierarchy=bishops and deacons (as opposed to the pope and cardinals that are over several churches)
Well, strictly speaking, that's all the RCs have - cardinals and the Pope are just bishops with particular roles. I don't agree with RC ecclesiology (because they have largely abandoned the conciliar nature of Church government) but this charge is unsustainable. For example, we have bishops called Metropolitan, Archbishop, Patriarch, even a Pope in Alexandria and yet they are all equal. Spiritually speaking they are all bishops and in their Synods they all have one vote, but in terms of organising the Church they all have different roles. A Patriarch is not, however, above a bishop in the way you appear to envisage.
Anyone can marry (Peter had a wife and is considered the first Pope)/no ban on marriage for church leaders, or for nuns or monks.
Well, with priests I agree with you, but you do realise this is just a discipline right? Rome does actually have some married priests, especially in her eastern rites. But as for monks and nuns, there is no ban. People choose to be a monastic knowing that celibacy is part of this and willingly accept it. If, later, they wish to marry they can leave without any consequence. Your characterising it as a ban is equivalent to me saying that I'm banned from being a civil engineer because I chose to be a software developer. I could always ceaseto developer software and go and train in civil engineering if I wanted to, after all. I also find it interesting that you dwell on the fact that Peter was married (prior to being an Apostle - nowhere in the history of the Church was marriage allowed after ordination, only before) whilst failing to mention that Paul chose to be celibate. Given the latter truth, how can you possibly be opposed to monastics who choose to do the same?
